Origami Exploding Pyramid Tower

[High Simple] How to fold a spring-loaded stack of pyramids that explodes when you press down and release. I didn’t mention it in the video, but these pyramids can also be used to play a balancing game where players take turns balancing pyramids on top of each other. Whichever player makes the stack of pyramids fall down loses (or gets eliminated if there are 3 or more players).
