As a final treat, the professor had one of his students do a demonstration using liquid nitrogen. Although it wasn't directly related to microscopy, he told us it is always a 'crowd pleaser'. He was certainly right about that. The student poured a Styrofoam cup full of the liquid. Then he placed various objects in to show us what would happen. First he froze a few cherry tomatoes and threw them on the floor to smash into bits. He also froze a penny, a new one made mostly of zinc, and had a young boy smash and break it with a hammer. He poured more of the nitrogen into a large Styrofoam container so he could put a small inflated balloon in to watch it freeze and shrink. When he removed it from the liquid, it quickly re-inflated and he passed it around to the children. JT's favorite part of the demonstration was when a frozen banana was used to hammer a nail into a block of wood.

I'm hoping some doors have been opened that will allow us to visit the school again, either as homeschoolers or maybe in the future when JT has started on his way in the real world as a young adult.
