Julia got some cool glow-in-the-dark paints for her birthday. She had a lot of fun painting in the dark. I had fun too. We didn't think the paints would keep overnight without drying out so we painted all 5 pictures the same night.
This picture didn't turn out quite like I was hoping, but the pictures really did look cool when they were done.
Turns out the paints never dry out, even on the paintings. But they do stop glowing after only one night.
