> Apparently liquid nitrogen ice cream makes smaller crystals or something and tastes better?

It's about how fast you freeze the ice cream so the crystals don't grow.

You can get N2 from a local gas supplier but a lot of grocery stores stock CO2 (Dry Ice) that can also be used for ice cream.

CO2 has the disadvantage of if you get it in the ice cream it makes it carbonated but the smoke looks like a witches cauldron so it looks cool imo.

My favorite use of dry ice is making Boo Bubbles:

1. Create a mixture of soap, water, and glycerin. This will make bubbles harder to pop.

2. Get a sealable container, poke a hole in the lid, the glue a tube in the hole.

3. Fill the container with water, then drop in pieces of dry ice. The CO2 should escape through the tube.

4. Stick the other end of the tube into the soap mixture.

5. Large bubbles will form with a cloudy gas of CO2.

6. Use towels to carry the bubbles, throw in the air, and combine with other bubbles.

I do this every Halloween. Kids get a kick out of it. A lucky few will stick around and learn about CO2, tensile strength, etc.

Surely there must be at least some flavours which could be compatible with carbonated ice cream. Cola ice cream, perhaps?
