Twitter user @RYUSO01 discovered something cool. If you draw something on a surface like glass or acrylic with a dry erase marker and pour water over it, the ink will lift and you can ‘animate’ it by blowing the water around.
I wouldn’t try this on a surface you don’t want to ruin in case it doesn’t work. I don’t think I would recommend trying on a porous surface either. Any tips or success stories, let us know in the comments!
