This week they showed a clip of the big balls with movement (them going up and down) and I thought it would be in this episode, especially since they said "we've taken our obstacles to the next level". Maybe it's in the next few episodes.
Either way if they did make it moving, it will be even harder to get though the big balls and that's tough as it is already. lol
I can't believe these people don't get hurt in some way, but the make great Wipeouts!
