Work and Energy

Elastic potential vs. Gravitational potential energy - - spring or dropper popper

Compress the spring on the popper or turn the rubber popper inside out and drop it. They both will spring upward showing the change in energy type. (If you want to do a numerical demo, I'll give you the spring constant of the popper and you can calculate and compare the actual height attained.)
