About This Product

The simple things are always so much fun. The original pop balls are back! To get them as high as possible, flip them inside out, squeeze the edges, and place on the ground. We’ve managed to get them popping about 1.5 meters high. Can you do better than us?

- Ages 5+
- Jump up to 1.5 m high
- Each sold separately

Snap-through buckling is a type of instability in which an elastic object rapidly jumps from one state to another. Such instabilities are familiar from everyday life: you have probably been soaked by an umbrella flipping upwards in high winds!

The inside-out shape of the dome poppers remains stable while the cap is held at its edges, but leaving the popper on a surface causes it to snap back to its natural shape and leap upwards. The snap back is not immediate: a time delay is observed during which the popper moves very slowly before rapidly accelerating.

The delay can be several tens of seconds in duration — much slower than the millisecond or so that would be expected for an elastic instability. Playing around further reveals other unusual features: holding the popper toy for longer before placing it down generally causes a slower snap-back, and the amount of delay is highly unpredictable, varying greatly with each attempt.
