This is one of my kids favorite activies to do! There are numerous ways to make bathtub paint. Most of the time I just look in the cabinet or cupboards to see which ingredients I have.
Edible Paint: Just add food coloring
1) Vanilla pudding
2) Cool whip
Non-edible Paint: Just add food coloring
1) Baby body liquid soap
2) Shaving cream
3) Clear bubble bath liquid
4) White Shampoo
Caution: Don’t use lotion or conditioner because it is made to soak in so it might stain your tub or grout.
Tip: Make sure and tell your children if you switch from edible to non-edible paint. My 16 month old was not too excited when he licked body soap!
