1001 things to do with Liquid Nitrogen

Not really 1001 things to do with Liquid Nitrogen, but quite a few besides frozen confections, including....

"LN2 also works great for sweeping and cleaning hard floors such as concrete or wood. Get a couple liters in a container, and dump it on the floor in the direction you want the debris to travel. It picks up everything in its wave and if it hits a wall, the wave will boil off and deposit the junk there. Now all you have to do is go around the perimeter and sweep up the clutter."

"Freeze a can of shaving cream and then peel the can away from the cream. Put the canless cream into someone's car. Let the oven-like heat from the car's sitting in the sun defrost the shaving cream. 2 cans will fill an entire car."

This suggestion sounds like it might be interesting to try:

From Dan Mcfarland (Holden, MA) I received the following:

"Dippin' Dots" Ice Cream!!!!!

Ever have any of that ice cream that's commonly sold at fairs that's a dish of little ice cream BB's? Here's how to make them (or a close approximation) with liquid nitrogen!

Start out with liquid ice cream (either make your own, or melt some that you bought at the store). Then just dribble the cream into a bowl of liquid nitrogen, stirring as vigorously as you can without splashing liquid nitrogen on your hands. As you stir, your goal is to keep the droplets of cream from floating and combining with adjacent droplets. After a while, you will have a slurry of little ice cream pellets mixed up with the LN.

After there's no more room for more pellets, pour off the LN and put your "Dippin' Dots" into the freezer. Be careful to let the ice cream warm up to freezer temperatures before you pop these little buggers into your mouth or you'll have them all super-glued to the inside of your mouth. Take it from someone who's done it.
