I'm proposing an adhesive substance that can be turned on and off at will with an electric current, using the doodad accessory (included -- batteries sold separately).
Smear some goop on your target surface, touch the electrodes of the Accessory Doodad to opposite ends of the goop and the molecules
of the material align to create adhesion. When dehesion is desired, touch the electrodes again to either end, reverse the polarity to disorient the molecules, the stickiness is undone.
In principle, developing the material should not be too difficult -- the technology exists. I need someone to help me out with the goop recipe. As I have previously mentioned, I was not a star pupil in chemistry.
Things that reverse with current.
But now, do it with glue. [nihilo, Jun 22 2006]
