Dropper Popper

The ultimate "Super Ball" is really only half a ball!

The Dropper Popper isn’t just a toy—it’s a hands-on physics experiment. Like a classic popper, it springs to life when you turn it inside out, but this version lets you explore the science of energy transformations in an exciting way.

Turn the popper inside out and hold it flat with the small knob. When you drop it from shoulder height, a little spin keeps it steady as it falls. Gravity pulls it downward, converting gravitational potential energy into kinetic energy. The moment it strikes the ground, the Dropper Popper’s elastic material suddenly snaps back to its original shape, releasing its stored elastic potential energy all at once.

That sudden burst of energy combines with the energy from the fall, sending the Dropper Popper leaping upward—often higher than your head! It’s a dramatic, memorable demonstration of how energy can be stored, transformed, and released, all in one simple, eye-catching motion.

Use it to spark curiosity in students about kinetic energy, gravitational energy, and elastic potential energy—or just enjoy the thrill of watching physics in action.
