I’m still driven crazy by the occasional need to detect the end on a roll of sticky tape. This stuff is now so thin that I can’t seem even to feel where the end is using my fingertips, certainly not when I’ve got only 20 seconds in which to wrap that last minute present.
Today’s invention is to avoid using that toilet-roll cardboard material to wrap the tape around. Instead, I propose that all (transparent) sticky tape be sold wrapped around a clear plastic ring. When you need to find the end, simply hold it up to the light and look through both the tape and ring.
