U.S. Toy 12 Hollow Plastic Eyeball Balls

Does it bounce like a ping pong ball?

I understand they are made of plastic. Soft or hard? Can they be squeezed so as to squirt water?

Are these hard or soft? i am looking for squirting eyeballs. These look like the one i misplaced. (And now Ican't see a thing! )

Are there different colors?
