The name says it all.
Here is a link to a list of great things to do with liquid nitrogen. My favorites are:
- 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. - Overclock your processor
- One of my favorite liquid nitrogen demonstrations is to place an
egg (raw in shell)in a container and cover with liquid nitrogen. After
the nitrogen has evaporated, take the egg out smash it with ahammer,
it appears to be hard boiled. As it cools it returns to white and yolk. - 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 it’s
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. - Take a ping-pong ball and poke a small hole in it. The hole
has to be tangental to the sphere of the ball. When poking the hole use a
pin and the pin should be almost flat agianst the ball. Basically you
want a hole in the side of the ball that will cause the ball to spin.
Submerge this ball into the liquid nitrogen and let it fill up. Place
the ball on a table and watch it spin. As the nitrogen goes back to a
gas it will rush out the hole and presto!! It’s pretty cool. If it does
not spin try placing your hand on it to warm it to get it started. - Sometime you may not have the time to cool the bottles in the
fridge before serving. In this case, fill all the glasses with warm
champagne, add a few ml of LN2 to each glass and serve immediately,
while the LN2 is still steaming. This one is really cool.
