Pierce just finished up his second of two one week "Geek Weeks" held in Hoboken. Basically, the Geek Weeks are day camp with geeky themes - right up Pierce's alley.
The first week was devoted to stop-motion animation. You can see the 3 minute movie Pierce and his team created, entitled "2030", here. Here's a still from the movie.
The second week was devoted to "potions" - various chemistry-oriented experiments. The pictures here show a selection of the results: green slime (borax, glue and food coloring), crystal growth (epsom salt crystals), and "tie dye" t-shirts (diffusing Sharpie ink with alcohol).
