Step 1: Watch the Video!
WARNING: These projects and results are depictions of my own personal experiences, which may vary depending on location, and modifications to project ideas. There may be risks associated with some of these projects that I'm not aware of. Liquid Nitrogen is -321F and can cause sever tissue damage and serious damage after prolonged exposure. Use of this video content is at your own risk.
Step 2: Futuristic Ice Cream (Dippin Dots)
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.
Step 3: Chill Pills
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.
Step 4: Noise Makers
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.
Step 5: Balloon Blowers
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.
Step 6: Chips That "Bite Back"
Now, it may look like they're boiling, but they're actually being cooled, to a ridiculously low temperature.
When the boiling stops, feel free to scoop them out, and onto a plate for serving.
If you try eating one of these right now, you might feel a sharp sting on your tongue, like the chip is trying to bite you back. But if you give them just a minute, then try chewing with your mouth closed, it should take your chip eating experience, to a whole new level.
Step 7: Liquid Oxygen
You can see that holding a flame into the can, will make it go out. But 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.
Step 8: Birthday Blowout
You'll notice that this time, the flame actually gets brighter. This is because the nitrogen has evaporated, and left the oxygen behind.
Pure oxygen is extremely reactive, and if we drop a candle down into the liquid, you can see it gets so hot, that the metal can actually melts in just a few seconds. Then explodes, spewing molten metal all over the place.
This is a trick that should be done outside, keeping the safety of you and your guests, as a top priority.
Step 9: Balloon Babies
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?
Step 10: Fly Babies
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, spread it's wings, and begin to fly.
Step 11: Kryptonian "Super Breath"
Pour in a tiny bit of liquid nitrogen, and get ready to put it in your mouth.
As long as you spit it back out immediately, you'll gain the Kryptonian power of super-breath.
Just make sure not to swallow, or take too long getting it back out. That probably wouldn't end well.
