This is pretty cool, it came as a bonus with a Monitor stand I purchased the other day. Its a piece of styrofoam in a plastic baggy. It is so much fun. I played with it for hours; swinging at the park, movies at the theatre, video games while it rained. I love my new styrofoam in a plastic baggy thing! But then I read the warning label, looks like I might have to get rid of the plastic baggy part, but the styrofoam I can keep forever!
