My favorite egg drop container design, ever! This is the inside view, and they had a lid to keep the egg in the middle cup. They knew the energy would travel through the strings and into the surrounding stuff before making it to the egg, from when we learned about sound waves.

I stumbled across this gem. Me in my old life. "911 what's the address of your emergency?" 15 years of this before I made the change to teaching. Best decision ever 💚
@WittmansWorld We are going to be figuring out the speed of marbles to later determine their kinetic energy. I need meters per second! Have them do meters on the back! We have a ton of yard sticks with inches marked on both sides.
