Pre-K Science Night!

Pulling the tablescloth out.

Hammering with a banana hammer. (frozen in liquid nitrogen)

Using liquid nitrogen to shoot a cork out of a small cannon.

The Finale, they put water in a bucket then added dishsoap. They they threw the remaining liquid nitrogen into the bucket and it made lots of bubbles. The kids really like this one!

I thought #3 was most impressive until I saw #4.

I remember uncle Paul taking a straw and hitting the straw into an uncooked potatoe... (he was trying to demonstrate that straw were dangerous) it went right in the potatoe... then he said, what do you think that would do to your eye??? I never thought that was possible... but it happened.
