00:00What if I told you there's a gas that can make you sound like a chipmunk?
00:04Yep, it's helium. Let's uncover some cool facts.
00:08Discovered in 1868, helium is out of this world, literally. It was first found in the sun's
00:15spectrum before we even knew it was here on earth. Helium sits right next to hydrogen on
00:20the periodic table, with an atomic number of 2. It's got a mass number of around 4,
00:26making it super light, so light in fact that it helps balloons float.
00:30This noble gas is colourless, odourless and tasteless. And get this, it doesn't react with
00:36other elements. That's why it's perfect for keeping things like your cereal fresh in those
00:41airtight packets. But helium's not just for party tricks or breakfast options. It's used in MRI
00:47machines to cool down the magnets, and in deep sea diving to help prevent the bends. Oh, and NASA?
00:54They use tons of it to clean rocket engines. So next time you inhale a bit of helium and sound
00:59like a cartoon character, remember, this gas does a lot more than just make you giggle.
01:04Stay curious everyone!
