  • Whether you get dry-ice from the store, or make it at home with a fire extinguisher,

  • here are 5 things you could do with dry-ice, but probably shouldn't.

  • For this first experiment, I’m using this bottle of fuel line antifreeze because it’s

  • 99% isopropyl alcohol. Like other alcohols, this stuff has to get tremendously cold before

  • itll freeze. So if we mix in some chunks of dry ice, you can see the ice boils violently

  • until the temperature cools down around -109F/-78.5C. Now weve got a makeshift

  • "cryogenic napalm", so let’s see what happens if we drop in a gummy worm. This sub zero

  • slurry is so cold, that it flash freezes the worm completely solid in under 20 seconds.

  • In fact it’s so hard now that if we try hitting it with a hammer, the whole thing

  • shatters like it was made of glass. The sudden transformation really is incredible, and you

  • might just have to break one to believe it.

  • Did you know you can use dry ice to make a popsicle? Start by making a groove or an indentation

  • in a slab of dry-ice about half an inch deep. Now try balancing a popsicle stick in the

  • center of the groove, then fill it up with your favorite drink. Youll see that the

  • instant it touches the dry ice, it will fog over with a misty white vapor. Now because

  • dry ice is only freezing the liquid on the bottom side, it’s going to take a few minutes

  • for the cold to penetrate all the way through, so just sit back, and enjoy the magic happening

  • right before your eyes. In a little over 10 minutes, you should be able to give your popsicle

  • a little wiggle and pull it out of the mold, but don’t lick it yet. This popsicle is

  • about 5 times colder than normal and will stick to your tongue. So dip it in a glass

  • of water to warm it up a bit first, then sit back and enjoy your delicious homemade dry-icicle.

  • Now check this out. We know that dry-ice is a solid that sublimates straight into a gas.

  • But what if we could turn it into a liquid? If dry-ice can be liquified, does it become

  • "dry water"? Liquid CO2 can’t actually exist in our atmosphere. But if were really really

  • careful, there is a way we can see it in it’s liquid state. If we fill a special preform

  • with a few pieces of dry ice and seal it inside, it will immediately begin pressurizing the

  • container. Once the pressure gets up around 75 pounds per square inch, an amazing thing

  • begins to happen. The ice starts to melt, and we can actually see what liquid carbon

  • dioxide looks like. Now we really need to watch this carefully because as soon as the

  • ice melts, the pressure can quickly rise to well over 1000 PSI and blow the container.

  • Before this one explodes, let’s watch what happens to the fluid if we carefully release

  • the pressure and remove the cap. The liquid is instantly transformed into dry-ice snow,

  • and you can see all the fluid has suddenly disappeared. Now to show you why this demonstration

  • is so risky, let’s put one of these containers in a cup filled with warm water, then get

  • really really far away. You can see exactly how clear and beautiful liquid dry ice is,

  • and at the same time, exactly how powerful it can be as well. Hopefully this gives an

  • idea of why this should only be attempted by professionals, if attempted at all.

  • Here’s one you can try at home. Drop some dry ice into a container of warm water to

  • get a thick vapor flowing, then lean in close, and suck in as quickly as you can. If you

  • do it right, it’s going to look really really cool. The white smoke is safe to breathe because

  • it’s just water vapor mixed with carbon dioxide. So go creep someone out with your

  • new supernatural ability. Now if you want to take it to the next level, try capturing

  • all the gas in a balloon. CO2 is what triggers your reflex to exhale, and if you try breathing

  • it straight, it will force you to cough, tingle your insides and leave you feeling a little

  • light headed.

  • For this next experiment we need to be out in the open and away from anything flammable.

  • You can see I’ve drilled a hole into this slab of dry ice and that’s where were

  • going to be dropping a coiled strand of magnesium ribbon. Now watch what happens when we light

  • the magnesium with a blow torch, drop it down in the hole, and seal it with another slab

  • of dry ice. It creates a vicious reaction that burns brighter than the sun. Which you

  • can see is enough to light up my yard in the middle of the night. Now the crazy thing about

  • this, is carbon dioxide usually puts out fires because it starves the fire of oxygen. But

  • in this reaction the magnesium is so hungry for it, that it rips oxygen right out of the

  • frozen CO2, and leaves behind a pile of black and white ash. The remains are mostly Magnesium

  • Oxide and Magnesium Nitride, but the black ash contains a lot of elemental carbon, which,

  • interestingly enough, is the same stuff you use for grilling.

  • Well there are 5 crazy and dangerous experiments you could do with dry ice, but really

  • probably shouldn’t. That’s it for now. If you liked these projects perhaps youll

  • like some of my others. Check them out at www.thekingofrandom.com

  • I get asked all the time where to get dry ice, so I'm going to tell you.

  • If youre over 18, it could be as easy as your local grocery store.

  • All the big chains seem to carry it, and all you have to do is ask for it when youre checking

  • out. So it's as easy as that.

  • I’ve also got a video right over here, showing how you could make it at home with a

  • carbon dioxide fire extinguisher, so maybe take a look at that one next.

  • I am constantly working on new videos to show you, and I’ve just sat down and planned out the next

  • 5 months worth. So "Sugar Rockets", the "Mini Arc Furnace" and "Fight Club Soap Molds" are

  • all on the list, because I know youve been patiently waiting for them.

  • Thank you for always being one of the first to watch my videos when they come out. I always

  • check to see if you like them, and what you have to say. So keep doing that, and I will

  • keep making them.

  • And I’ll be looking for you in the next project video. See you then.
