Hi all
I'm sure you've all seen and some of you have probably used these aqua draw mats of various shapes and sizes. Basically you fill up a pen with water and 'draw' on the white board/paper. Magically the picture appears. To re use just wait till the page dries and it turns back to white.
I'm pretty sure its just a picture with some kind of white chemical painted on top, which turns translucent when hydrated with water or saliva.
But what is this chemical?
Info on this on the net is really hard to find.
