Retirement

Do you ever feel like: man I wish I had a tire swing?

No?
Then you aren't really living life to the fullest. I've wanted a tire swing at least thirty times today.

Well then this idea will make you an instant gazillionaire. It's simple, implementing a a blow up inner tube and a rope outfitted with a hook and a magnet, you can  take the rope swing anywhere with you.

All you have to do is throw the top over a branch that can hold your weight, blow up the inner tube, and clip it together, using the magnet as a security precaution.
