Teflon Blu-Tack

We call the blue sticky stuff that you use to attach posters to walls "Blu Tack". The stuff they coat non-stick frying pans is called "Teflon". Nothing sticks to it. Teflon Blu-Tack is a product that provides the benefits of both with none of the side effects. No greasy marks left on posters and no need to use special nylon spatulas to turn your eggs over.
Anything you try to stick in place just fall away. That model you are trying to hold together while the glue dries will simply disintegrate. The paper clip holder you have been trying to attach to your desk will effortlessly glide off. NASA is considering using it instead of explosive bolts because of it's less dramatic failure modes (although the same engineer who proposed the idea also expressed concern of its lack of "success mode").
