-hold 2 piece fishing rods together
-Pant gaters....holds my jean pant legs down when I put on my chest waders
I have used duct tape for the gater part as well
-used to hold a flapper onto the exhaust of a friend's tractor....had to replace often
-Hand cuffed my niece just cuz she did not believe I would do it. She was stuck for about 30 seconds till the whining became unbearable
-makes our lawnmower keep running even when you let go of the bar
-ditto with the snow blower
That is all I can think of now....
