I went to a comedy show a few years ago and the comedian had a toilet paper launcher. He took a leaf blower and had some sort of dowel attachment on the end. The rolls were then put on these dowels with the loose ends following the air current. When he turned it on, it shot the paper at least 10 feet.
The one that this guy had had two rolls so that it created a stronger air current in the middle.
