Need to carry out an act of vandalism, but find yourself wracked with guilt?

Well, worry no more, as an engineer in the US has developed a spray-paint can that contains dry erase ink – like the kind you’d wipe clean from a white board.

Errant tags of who woz where and when and ill-fated declarations of love can be fixed in an instant, while dodgy parkers can learn all about your fury without you permanently damaging their car. DEP Spray will give you the delinquent fix you're looking for.

The cans work just like white board makers, so the spray paint will only wipe off certain surfaces. But as long as you vent your rage against the man on smooth materials like glass or metal, you can clean off any trace of your protest or message.

But beware walls – the porous concrete and plaster makes the ink hang around, and spells vandalism as far as the letter of the law is concerned.
