00:02So cool, science!
00:10How do I keep my shoes from smelling?
00:13Well, that's a wicked cool question, and I got a wicked cool solution.
00:16If your shoes smell so bad that they could gag a vulture.
00:20Well, which is pretty bad, because, I mean, they eat rotten meat.
00:23Maybe your shoes are so bad they're actually stopping you from being able to make money.
00:27You know, like maybe a hag. You know, part-times as a librarian. I mean, a witch.
00:34Because today, I am going to show you how to stop the stench that stole freshness,
00:39and a way you won't have to pay to keep the odors away.
00:45And of course, all you have to do is take a teaspoon of baking soda,
00:49and put half of it in each of your shoes.
00:56Then, shake it all about, and in the morning, give your shoes a sniff with your snout.
01:03Whoa! Now check that out, man. The baking soda made the smell of the shoe go away completely.
01:08Yeah, it's gone. It's totally gone. You won't have to smell the smell of the shoe anymore.
01:11It's totally and completely gone. The baking soda's totally completely gotten rid of it.
01:14And unfortunately, it will not get rid of a hag, you know, who part-times as a librarian.
01:19I mean a witch! Totally meant a witch. I totally, I 100% meant witch.
01:24Yeah. Witch.
01:30So, how does the baking soda actually make your shoes smell better?
01:34And, how does it stop bacterial growth?
01:37Well, don't look at me. Take a closer look at this.
01:42Bacteria are any group of microscopic single-celled organisms that lack a membrane-bound nucleus,
01:47as well as other internal structures known as prokaryotes, which consist of bacteria and archaea.
01:53When conditions are just right, such as plenty of food, an abundance of water, as well as the right temperatures,
01:59prokaryotes speed up in division.
02:01So, if you step in a puddle, the bacteria that are already feeding on your fatty sweat get an abundance
02:06of water
02:06and increase their division, as well as waste product.
02:10Which is why your shoes start to build up an odor.
02:12Adding baking soda to your shoes creates an alkaline environment,
02:15which interferes with the bacteria's functions that are necessary for life.
02:18This causes the bacteria to die and the baking soda neutralizes these acidic molecules,
02:22which reduces the odor in your shoe.
02:25Bacteria evolved sometime around 3.9 billion years ago, most likely from an RNA ancestor,
02:30which was nothing more than a capsule with RNA instead of DNA and maybe a couple of ribosomes for replication.
02:36Life got its start near underwater thermal vents, where prokaryotic life got its energy from chemicals.
02:42We call these the chemotrophs.
02:44Some of these chemotrophs split off around 3.8 billion years ago and evolved the archaea group.
02:48Other chemotrophs rolled the thermal gas plumes to the surface of Earth's oceans,
02:52where a few of them evolved the ability to obtain energy from light about 3.5 billion years ago.
02:58So now you know more about prokaryotic life.
03:00You know, being able to take the shoe smell away simply with baking soda is why science doesn't stink.
03:09…and your phone number was not a mere weight, and…
03:10…to make point for binos…
03:10…and you know…
