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)

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.

Step 3: Chill Pills

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.

Worth noting that swallowing liquid nitrogen can cause terrible stomach injuries:

I've played with liquid nitrogen quite a bit and spent all day dipping an ungloved hand into the flask (isn't the Leidenfrost effect great) but I would hesitate to suggest anyone puts liquid nitrogen into their mouths.

Aside from that, this is a great collection of fun liquid nitrogen demo's - thanks.

An 18 year old girl in the UK called Gaby Scanlon had to have an urgent operation to remove her stomach after drinking a cocktail made with liquid nitrogen.

As for putting it in your mouth, someone else had to have their stomach removed a few years earlier, so overall, it's just not a good idea folks :-}

so, this is full of awful irresponsibility. I may as well add another, just in case anyone doesn't off themselves with the whole liquid nitrogen in the mouth bit. Fill a plastic bottle with the liquid nitrogen and screw the cap on tight. Really guys, LOX is used as the oxidizer in rockets. Please for the sake of your mothers, don't drop candles in it.

I wouldn't want to show kids how to put liquid nitrogen in their mouths and molten metal is usually a bad idea at parties...
These things seem like more of an outdoor weekend thing.
Liquid nitrogen is not difficult to get but you should have a good container to store it or it won't be around very long.
