The king of kid science is Steve Spangler. He has a number of amazing videos on 3 YouTube channels: Sick Science, The Spangler Effect, and Spangler Science TV (where he’s on Ellen quite a bit). He sells some interesting kits on his website. We got Fast Physics which basically includes some popsicle sticks, a 20 foot string of beds, a couple other things and some instructions. In some ways it was a bit underwhelming but man, did we have fun! The videos were surprisingly hard to find but Newton’s Beads and Popsicle Stick Chain Reaction are pretty awesome. Ari’s done them (with help) a number of times. The Magic School Bus Chemistry kit was a bit more fun for the kids with bright colors and clearer instructions.
