Bathtime with shaving cream and food colouring. Perfect for a rainy day, or so I thought. Not sure if I put in too much food colouring, or something else, however this was the biggest mess ever.
Shaving cream- yes, much better to paint with, unless you go to shoppers drug mart where all of a sudden all shaving supplies are under lock and key. When did this happen? Adding food colouring not so much. If you are going to encourage your children to paint with shaving cream, make sure you don't plan on washing them up after playing with this. Not possible, unless you empty the tub, and start over.
Overall..I don't recommend. Just shaving cream works, or better yet turn off the lights and just use glow in the dark stick.
