Hopefully E wants a batman party Batman Ice Cube Tray. Here’s a fun geek party trick: Freeze tonic water in your Batman Ice Cube Tray. The quinine in tonic water will cause the bats to glow blue under black light.
Fun art project with the kids! Easy abstract painting that anyone can do! Just blob the paint on the canvas in random spots and blend! (would be interesting how students could make different pictures w/ the same colors and same blob positions)
