An Idea Whose Time Has Come?

This may be more fun than silly string in the bedroom. Now there is a spray on condom product that goes From Liquid Rubber To Sweet Love in One Second:

A German firm has developed a spray-on condom for all your lifestyle needs. The liquid condom comes in an aerosol can that you spray onto the organ in question. A few seconds later, the liquid solidifies into the familiar latex and forms a tight seal. The company says it's a great time saver and is easier to use than traditional condoms.

The only thing I can't find out in all this hype is, "How do you get the damn stuff off?"
