If you are considering making stilts from your Crocs, you might like to know that Coke Zero cans are not as sturdy as Mug Root Beer cans. Isaac and Ethan highly recommend a stronger can, so your stilts don't collapse. I absolutely LOVE the creations these boys come up with. They make me smile! The white tape, I was informed, is not for structure. It's only to make them look cooler (as if homemade stilt shoes weren't cool enough to begin with!).
