  • The demonstrations you are about to see are for educational and entertainment purposes

  • only, and are not intended to be duplicated.

  • Get out your container of liquid nitrogen, and grab a box of neapolitan ice cream. This

  • is the type of ice cream that has 3 flavors in one, so go ahead and separate the colors

  • into different containers, and give them a couple of minutes to melt. In the meantime,

  • we'll need to fill a bowl, with liquid nitrogen. This stuff is -321ºF (-196ºC), which means

  • it well below the freezing point, of your party guests. Now if you try dripping your

  • flavors in, one drop at a time, you'll notice they instantly bead up, and freeze solid.

  • When you've got all the flavors you need, simply scoop the tasty pellets into a serving

  • bowl, and voila! You've got a futuristic ice cream, ready to serve, and enjoy.

  • Load up a bowl with mini marshmallows, and sprinkle liquid nitrogen over the top. The

  • marshmallows should freeze instantly, but go ahead and let them soak for about 30 seconds

  • just to be sure. The end result is a sub-zero "chill pill", that's perfectly fine to eat,

  • and lets you see your breath when you crunch into it. Now, if you flash-freeze a larger

  • marshmallow, rather than eating it, try placing it on a plate and giving it a smack. It'll

  • shatter into a thousand pieces.

  • For this trick you'll need a glass bottle with a narrow neck, and a party horn with

  • a little hot glue, added around the bottom. When it gets placed in the bottle, it should

  • make a nice, snug fit. Now carefully pour the liquid nitrogen, so the bottle is a quarter

  • full, followed by a shot of hot water. You can see that when the horn is pressed into

  • place, it becomes a crazy noisemaker, that blows all on it's own. If you get a few of

  • these going, you can really make some noise.

  • When there isn't enough pressure to keep the horns going, try adding more hot water to

  • the bottle, and place a balloon over the top. There will still be enough pressure shooting

  • up, to inflate the balloons, all on their own. It will save you the effort, and the

  • gas inside is completely harmless.

  • Cut the top off an empty soda can, and fill it up with more liquid nitrogen. If you let

  • the can sit for a few minutes, the extreme cold, will pull oxygen out of the air, and

  • trap it at the bottom. Now try dipping a super strong magnet into the liquid, and when you

  • pull it out, you'll have liquid oxygen stuck to the bottom. At least until it warms up,

  • and boils off.

  • Blow up a bunch of little party balloons, and soak them in a container of liquid nitrogen,

  • so they shrink down to nothing. Then quickly scoop them all into a bowl, and stand back

  • to watch the magic. Rising from a layer of mysterious flowing fog, your little balloon

  • babies, begin to grow right before your eyes, spilling over and covering the table. They

  • grow up so fast, don't they?

  • Fill one of your small balloons with helium, and shrink it down in liquid nitrogen, like

  • you did the others. Scoop it out and place it down on a table to see what happens. You'll

  • notice that after a few seconds, it suddenly pops upright, then takes off like a little

  • UFO. Your friends should be impressed, to see your little creation grow up, and begin

  • to fly.

  • Well now you know 7 different party tricks, with liquid nitrogen. If you liked this project,

  • perhaps you'll like some of my others. Check them out
