Itch Litmus

A spray that will show your partner where the itch is

Do you have a problem telling your partner where the itch is - all that "up a bit...ooh, no, right a bit...too far, left..."

I want a spray that changes colour when the skin it's sprayed on is itchy. You know, like that stuff you can swill round your mouth that stains the plaque on your teeth. A quick squirt and the itchy bit shows up a virulent orange.

All we need is some chemical correlate of itchiness - histamines, perhaps? - and some safe chemical that reacts to it.

       Ok...Well for a start, a 'regular' itch is not caused by chemicals - rather by movements of small hairs on the skin. And secondly - you tell us what chemical works, and we vote, otherwise there really isn't an idea here.

       But during a good backscratch the itch moves. How are you going to chase the itch? I like getting to tell where to scratch.

       I take back the no invention thing - it's more of a WIBNI.
