While I've been doing the EXPLODING PUMPKIN for years at school, Ellen allowed me to perfect the formula. It's fun to share the original version (circa 2008) and give a shout-out to Ellen and her team for allowing me to take it to the next level. Just in case you want to nerd out, we're generating acetylene gas in the pumpkin using calcium carbide and water. Of course, a little spark from Ellen and you've got a real audience pleaser. Just let me know if you want to see the big finale. | Steve Sp
