An eye popper, rubber popper, hopper popper or jumping popper[1] is a children's toy. It consists of a small, dome-shaped piece of rubber or similar material resembling a half of a rubber ball; the shape of a smile is often imprinted on the dome. When pressed, the object inverts and becomes unstable and, after a few seconds, undergoes snap-through buckling to pop back into its original shape, making a loud popping sound.[1][2][3] If resting on the ground when this happens, the toy will fly several feet into the air. It can also be thrown on the ground, causing it to pop upward.[3] The eye popper's behavior resembles the process by which a ball compresses upon hitting a hard surface.[4]
