Thermochromic pain is a heat sensitive paint that will turn invisible when you breath on it. I used that and some old t-shirts. The thermochromic stuff needs an adhesive to stick to fabric. If will appear and disappear on the white tshirt.
I sewed the t-shirt using a styrofoam head to make sure it was symmetric
