Close encounters of the Chemical Kind

We had a great turn out for our second summer program event, “Close Encounters of the Chemical Kind.” Just how close was the encounter? People were sprayed with invisible ink, splattered with liquid nitrogen, and everyone went home with a silver (really zinc-coated) penny, a hand-made super ball, and a cool wax painting. It was described afterwards as “really, really, really, really cool,” and not just the part where Bill Bosworth dumped liquid nitrogen (the coldest object on earth) all over the floor. The kids learned about the properties of the elements, about how molecules can effect volume, and how two liquids can become a solid. For more pictures of the event, check out our Flickr page. Leave us a message to let us know you were there!
