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
