Bicycle Tube Jump Rope

It has been a long, cold, and snowy winter.  That usually would not keep me from getting out, but I stay at home with our children, and the youngest is only 9 months old.  I don't want to expose her to the cold and elements.  So, I have had cabin fever quite a bit.  My bones and muscles are feeling pretty tired and weak lately.  To help alleviate this I've been doing a bit of indoor cycling.  I learned to ride rollers last week.  A cyclist needs to do more than just ride the bike though to really stay in shape.  The body needs to do different movements, and be stretched more.  I'm taking it back to the basics:  sit ups, push ups, jumping jacks, pull ups, and jumping rope.  I was trying to think of other ideas of how to use old tubes when I grabbed one I had lying around, and just started jumping rope with it.  It worked fine without handles, but I really wanted to get handles on it, so of course old grips were the answer.  My local bikeshop, Bikesport, supplied these excellent quality Bontrager grips free of charge.  I wanted to show the rope in action to show that it works just fine.  

What else are old bicycle tubes capable of making?  I've made an air block for the door, and now this jump rope.  What have you made with them?  Please tell us.
