A little chemistry, a little physics and a lot of wet, messy fun. For Gabe's birthday party he received a miniature Toy Story water park. It comes complete with slide, buckets, small pool, shower (weird...yes?) and a Woody toy. Woody changes colors in different temperatures of water, there are different levers to push to flood the slide with water and work the shower. A lot of science for a child's little toy. And after my initial apprehension of all the mess, this activity keeps Gabe's attention longer than I usually need to get dinner ready!
