Slingshot tip!

If you have a slingshot with the surgical tubing bands on it and have ever tried to replace them they're just about impossible to put on. However if you dip the forks in rubbing alcohol they will slide on like butter on ice, it really works here is a video on this subject:

Literally the best part of that whole video was the sound effects at the end
It reminded me of Crocodile Dundee calling for back up. 

I'd be a little scared to but rubbing alcohol on there and know that it was eating the tubing. When I had a wrist rocket I used to just moisten the forks with saliva and slide the tubing on. Let it dry over night and good to go.
