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.
