00:00I just found the most insane science gadgets like a blaster that fires real
00:04lightning, gloves that let me climb walls like spider-man, or a plasma reactor that
00:09lets me shape raw energy. And up first is this gadget that creates 3D holograms.
00:13This gadget is a 3D mirror scope and it can turn any object into a hologram.
00:19This gadget is made up of two curved mirrors and when the real object is placed
00:24at the bottom and you close it up, the mirrors reflect light onto each other
00:27creating a focal point at the top which makes the floating image you see.
00:31You can put anything in it. You want a cookie? Psyche, it's not real.
00:34Want to get rich? Psyche, you're broke. But this next gadget is real.
00:39I'm holding a tube of plasma in my hand. It might not look like it, but let's charge up the air around my fingers to 100,000 volts and see what happens.
00:48That glow is crazy. So these are tubes of luminous gases and they light up when they come near the Tesla coil.
00:55So how does it work? You can think of the atoms in this tube as a jar of fireflies.
00:59Right now, the fireflies are sleeping. But when it gets close to the Tesla coil, it's like a mini thunderstorm.
01:05The Tesla coil emits energy that excites the atoms, which knocks off the electrons and these collisions emit light energy.
01:12This whole entire process is called ionization. And different gases glow different colors when they turn into plasma.
01:19Neon glows orange. Argon is a light purple. Helium glows white. Krypton glows blue. And xenon glows an aqua color.
01:27One of our later gadgets will use this luminous gas to create something you've probably never seen before.
01:33I can bend water with this next gadget, the Chinese spouting bolt, turning calm waters into a raging wave.
01:46Sadly, I'm not the next avatar. I just know how to use science.
01:50So this bolt and the handle is made of bronze, which vibrates easily.
01:54So that means if I start rubbing these handles, it will start creating friction, which is then translating into a vibration throughout the entire bowl.
02:05These vibrations cause the entire bowl to resonate, creating ripples.
02:09And at higher frequencies, the energy is so strong, it throws the water upwards, creating the spouting effect.
02:16And the harder I rub, the more she squirts. Yeah!
02:20This next gadget is able to make things levitate. If we put in this piece of foam, you can see it starts floating.
02:27And it's not using any strings at the top or the bottom. Instead, it's using sound waves to keep it afloat.
02:33If you listen carefully, you might be able to hear a slight buzzing sound.
02:38There are two transducers, one at the top and the bottom, which are basically like high-frequency speakers.
02:43They produce an ultrasonic sound wave. These sound waves travel in different directions,
02:48but share the same frequency and amplitude. This creates a standing wave pattern.
02:53In this pattern, there are stable points called nodes.
02:55And these nodes create tiny invisible pockets of air pressure strong enough to cancel out gravity.
03:00So when you place a lightweight object in one of these nodes, they should start floating.
03:05It's completely floating. No strings attached.
03:07So now we learn to bend water and sound.
03:10Next, it's time to harness the power of fire.
03:13This gadget turns fire into electricity.
03:16So you can charge your phone and doom scroll TikTok even in the wild.
03:20It's called the BioLite stove.
03:22And all we have to do is stuff our wood into the hole and start our fire.
03:26As the stove burns, it generates electricity through the thermoelectric generator inside.
03:33And we will know once it's generated electricity if we press this button and a fan turns on.
03:39Ah, it's creating like a vortex effect. That's kind of cool.
03:44So the electricity generator works by having a hot side inside the fire chamber right here.
03:50And there's a cool side inside of the fan chamber right here.
03:54The temperature difference creates a flow of electrons, which generates electricity.
03:58This is called the Seaback effect.
04:00So the hotter the fire burns, the more power is generated.
04:04Normally, I wouldn't burn fire inside just because of all the smoke.
04:08The other cool effect of these fans is that they pump in more oxygen, making the fire burn hotter and cleaner, creating a smokeless flame.
04:17So let's test if this is actually going to be able to charge my phone.
04:22Oh, it's charging. It's charging.
04:25Let's go.
04:25Any excess energy that's not being used to charge will be stored in the internal battery bank.
04:31And this thing comes with attachments.
04:33It's got a grill right here.
04:34With the grill, we can make some grilled cheese.
04:37Let's flip it around.
04:39It's a very burnt grilled cheese.
04:42The cheese of truth.
04:44And we'll let it cook a little bit because I like my cheese drippy, bruh.
04:47Our cheese is now very drippy.
04:50We also have another attachment that we need to brew tea for our next gadget.
04:54This next gadget is an assassin's tool used by the ancient Chinese.
04:58It's not a knife.
04:59This is the assassin's teapot, and it allows you to pour multiple drinks from the same spout.
05:05So how it works is, pretend we're at a tea ceremony, which was very popular back in the days.
05:10An assassin would pour tea for themselves and drink it to gain their enemy's trust.
05:16Then they would pour the poison for their target.
05:19And since both liquids came from the same teapot,
05:22the enemy would drink the poison tea and no one will expect a thing.
05:26Mission accomplished.
05:28So how it works is, the teapot has two chambers inside and two holes near the handle.
05:34One up here and one down here.
05:36By covering a specific hole, you control the air pressure and surface tension.
05:40Allowing one drink to pour while keeping the other sealed.
05:43It's kind of like how you can trap water in a straw by covering a hole.
05:47But once you let go, the liquid shoots out.
05:48So covering the top releases a blue drink.
05:51Covering the bottom releases a red drink.
05:53And leaving both open, you mix the two drinks, which would make purple.
05:58But if you're not trying to unalive anyone, this teapot would make a great party trick.
06:02Because you can put tea in one chamber, milk in another, or serve both combined to make milk tea.
06:07How is this table floating?
06:09It looks like it should collapse, but somehow it's rock solid.
06:13This is a tensegrity table.
06:15A structure that seems impossible at first glance.
06:18But there's no trickery, just pure physics.
06:20It's actually only held together by a few strings, but it holds a surprising amount of weight.
06:25It's the same engineering concept using Olympic arenas, bridges, and even NASA space structures.
06:31But how does something so flimsy hold so much weight?
06:34It all comes down to the balance of forces.
06:37In the center, the solid metal parts of the table are in compression, meaning they're pushing down.
06:43But the string over here is in tension, that means it's pulling up.
06:47So these forces perfectly counteract each other, keeping the whole structure floating.
06:52And the outside strings are there to provide stability, so the whole thing can stand up properly.
06:57But we gotta find out how strong it really is.
06:59So let's try a phone, all right?
07:01No problem.
07:02Now let's try a laptop.
07:03No way.
07:05We gotta test the weight limit.
07:06So let's start by putting some dominoes on top of the laptop.
07:10So the laptop is about 1.5 kilograms with the case.
07:14Each domino is five grams.
07:16So we'll just keep adding onto the topples.
07:18While I'm adding weight, let me tell you how you can get your own tensegrity structure for only one penny.
07:24You heard me right.
07:25Only one cent.
07:26Quantities are limited, and it's first-come, first-served, so listen up.
07:29And all this is possible, all thanks to Odoo.
07:32We added 10 dominoes so far.
07:33So Odoo is an all-in-one business tool with apps like accounting, project management, and website build.
07:39The first app you use is free for life.
07:42You guys probably already know Odoo because we've done two huge give-back events before.
07:46But this time we're doing it bigger and better.
07:49We have 100 DIY tensegrity building kits ready to get, all for one cent each.
07:55And in the future, the more you show love to Odoo by making your own free website, the more we can give back to you.
08:01For the website where you can buy this stuff for Ascend, I built using Odoo with zero technical skills.
08:06Odoo just asked me for a few prompts, made a ready-to-go template, and I just dragged and dropped what I needed.
08:11Odoo even gives you a free custom domain for one year.
08:15So if you ever thought about building a website, this is the easiest way to start.
08:18And it's free, so there's nothing to lose.
08:20Now go to halfago.odoo.com to grab your tensegrity building kit for one penny.
08:25And check out Odoo's tools while you're there.
08:27And if you want to start your own website for free, just click the link in my description or at the bottom of my website.
08:32Enjoy your gift.
08:33Let's just keep piling it on.
08:35You think that it's going to hold?
08:38Oh, it's tipping.
08:42This table is invincible.
08:44Let's just see if we can sit on it.
08:46Here we go.
08:48I broke it.
08:52No fat jokes, please.
08:53Now that you've witnessed the impossible, it's time to see the invisible.
08:57This next gadget allows you to see a world that's invisible to your naked eye.
09:01This is a tiny microscope.
09:03And unlike a traditional microscope, you can take this anywhere and look at anything at the microscopic level.
09:09And the best part is that it even has a screen on it.
09:11So you don't have to like squint and like try to look with one eye.
09:15We have a few slides of specimens.
09:17So this one is the mouth of a fly.
09:20Let's see what that looks like under the microscope.
09:22We just need to point it at our object here and use this style to focus.
09:28Damn.
09:29That's crazy.
09:30You can see the individual hairs.
09:32Because it's so portable, we can actually use it to look at anything.
09:35Let's look at our phone.
09:37Whoa.
09:38You can see the individual's red, green, and blue pixels that make up all the colors.
09:42All right.
09:43I'm going to get a human specimen right here.
09:45Please turn it upside down.
09:47Get on there.
09:48Yeah.
09:49Okay.
09:50There we go.
09:51Get up there.
09:52Okay.
09:53All right.
09:54Let's take a look at your skin.
09:55Whoa.
09:56All right.
09:57You got a lot of micro hairs.
09:58All right.
09:59All right.
10:00Let's take a look at your eyes.
10:01Whoa.
10:02There's a lot of like texture in your eyeball actually.
10:05See what hair looks like.
10:07Very healthy looking hair actually.
10:11Very clean strands of hair.
10:13All right.
10:16Same time next week.
10:17This microscope is awesome.
10:19You can look at anything.
10:20Even your tiny little piece.
10:21This gadget lets you turn into real life Spider-Man.
10:24It's called the Grabo and it's a vacuum powered suction tool.
10:28So a regular suction cup works by pressing out air.
10:31But the Grabo actively sucks out even more air.
10:34Making the outside air pressure push down even harder.
10:37Usually the Grabo is used to lift furniture or big slabs of concrete.
10:41So even if you add more weight, it can still lift.
10:44The Grabo claims to lift 370 pounds.
10:47Which means it should probably lift my weight.
10:49Let's put that to the test.
10:50Here we go.
10:51Gonna lift my feet now.
10:53Yo.
10:54Yeah.
10:55Yo.
10:56That's pretty strong.
10:58This got me thinking.
11:00What can you do with two Grabo's?
11:02If one Grabo is enough to lift my entire body weight.
11:05I can use the other Grabo to move up.
11:08Suck on.
11:09Hang on to that one.
11:10And then keep moving up.
11:11So I can climb walls like Spider-Man.
11:13Time to reveal my secret identity.
11:15I was Peter Parker all along.
11:21It's a lot harder than I thought.
11:23So I think we need something to support my legs.
11:25Okay.
11:26We made some major upgrades.
11:27We have industrial grade ratchet straps.
11:30So I can rest my foot.
11:31I've also changed to barefoot shoes.
11:33Which allows me to flex.
11:35And climb the walls more easily.
11:37Hopefully these upgrades together.
11:39Will allow me to scale the wall.
11:41Here we go.
11:42My goal is to touch the yellow part.
11:45Great.
11:46Oh shoot.
11:48Alright.
11:49Here we go.
11:50We gotta lift one foot.
11:51Alright.
11:52Okay.
11:53Good.
11:54Moving up.
11:55Oh.
11:56Yeah.
11:57This is pretty sick.
11:58Going pretty high.
11:59Now we gotta go up with this.
12:01Alright.
12:02Here we go.
12:03Punch.
12:04Mission accomplished.
12:05Now we gotta come down.
12:10Spider-Man.
12:11Now that's the power of science, baby.
12:13Each time I moved up, I was super scared that one of these would give out.
12:16And once I got up there, it looked pretty high.
12:18But thankfully, science kept me alive.
12:20This is a lightning gun.
12:24You see that?
12:25It's actually called a Tesla coil blaster.
12:26And the Tesla coil works by converting the electricity from these lithium ion batteries
12:31into high voltage, high frequency electricity.
12:34So your toaster runs at 120 volts.
12:37But a Tesla coil can run up to 100,000 volts.
12:41And the big Tesla coil can run up to 1 million volts.
12:45And since this is handheld, you can shoot this at anyone, anywhere.
12:49Should we try?
12:54It stings a little bit, but it doesn't really hurt.
12:56And after I get zapped, I can feel a surge of electricity.
13:00So if the Tesla coil produces such high voltage, why is it still safe to touch?
13:04It's because voltage is only the electric potential.
13:08But just like you, you probably won't reach your potential.
13:11So imagine electricity is water flowing through a hose.
13:14Voltage is the water pressure.
13:16And amps is the amount of water flowing through.
13:19So even if the hose has really high pressure, if there's very little water flowing through,
13:24it's not going to hurt me.
13:25And the Tesla coil is safe to touch because it has really low amps.
13:28But that brief spark is still enough to burn things.
13:31For our first experiment, we can see the pattern of lightning if we use our Tesla coil on the receipt.
13:37Because receipts are heat sensitive.
13:40Oh my gosh, it's immediate.
13:43You can immediately see the lightning pattern forming.
13:47It was completely white before.
13:49Now look at all the burn marks.
13:51Let's see if we can pop this balloon.
13:54Impressive.
13:55But can it allow you to match?
14:00Damn.
14:02Let's find out if a Tesla coil gun can roast a marshmallow.
14:08The Tesla coil gun is cool, but our next gadget uses electricity in an even more interesting way.
14:15This gadget is one of the coolest things I've ever seen.
14:17It took me a long time to find where to get it.
14:19But it was worth the wait.
14:21Just take a look.
14:26Look at that!
14:27Does that not look magical to you?
14:28So this is called a toroid plasma reactor.
14:31And toroid is just the name of the donut shape, which is what you see.
14:35And with this, we can control the power, which then controls the shape of our plasma.
14:40If you get close to it, you can actually hear the sound of plasma vibrating against a glass.
14:49But if I pick up the globe, the light eventually dies.
14:55So what's going on here?
14:56How does this work?
14:57There's two parts to this.
14:58The machine down here is generating an electric field.
15:01Kind of like an induction stove.
15:03That's why when I bring the globe close to it, it will start to light up.
15:07Because the electricity is ionizing the xenon gas inside and turning it into plasma.
15:12The exact same process with the luminous gas experiment earlier.
15:15But what makes this gadget 10 times cooler is how the toroid, the donut shape, is created.
15:21And that's through these coils right here.
15:23These circular coils are creating a magnetic field, which is influencing the shape of the plasma inside.
15:30That's why as I turn the power up or down, the shape changes.
15:35And if you get it just right, it creates a perfect toroid.
15:38These gadgets prove that learning about science is not lame.
15:41Instead, it's the closest thing we have to real magic in real life.
15:45So click here to watch another Science Gadgets video.
15:48And click here to watch a video that YouTube thinks you'll love.
