Those silly hamsters get to run around in their plastic round balls all day long. While you’re stuck just walking on the ground like a normal person. Why should the hamster get to have all the fun?! Now you can have your own clear ball to run around within. Of course, to run around like a hamster it’s going to cost you, one of these is priced at $710 and then to purchase the blower to fill up the ball it’ll cost you $199. It’s able to work in a pool as small as 8 feet in diameter and tough enough to withstand a pebble filled beach.
