Eye popper
Appearance
An eye popper, rubber popper or hopper popper is a popular 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 toy inverts, but after a few seconds, it pops back into its original shape, making a loud popping sound.[1][2] 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.[2] The eye popper's behavior resembles the process by which a ball compresses upon hitting a hard surface.[3]
