I think i've made my point. (I was going with Duct-tape for most of these, clear scotch tape was not what I had in mind, although it would still work for a lot)
You know, I heard somewhere that the company that makes Duck/Duct tape is having a contest where you design the best prom dress. The catch: You have to use duct tape to make the entire dress. The winner gets... I think a money for a scholarship?
So that's a pretty good use for duct tape: A Prom Dress.
Making a house out of duct tape would be pretty cool. Not sure how well tape works as an insulator.
Hmm...That'd take a LOT of tape, and the roof would definitely sag...although if you had enough support posts, it would stand. You'd have to make duct tape beams first, layer the duct tape together 2 strips in a row and make them very thick, then you'd have to lay them out, and securely tape them to each other...XD
