Thanks to a post at Play at Home Mom I got the idea to bring glow sticks in the bath tub. I got these at Dollar Tree they are the necklaces/bracelets so you get more, I think we ended up with 12. I am still learning how to take pictures in the dark. Check out hers they are much better and give you how truly and exciting the it is. C and R stayed in for about a good hour if not longer. With the lights off. I don't think any cleaning got done, just a whole lot of fun! Sometimes we need that more then being "clean".
