Intro: Bathtub Soap Crayons
These bath crayons are easy to make, and most importantly, kids love them! I used a bar of almond soap that was given to me around Christmas, but you can use any white bar soap as long as your kids don't have a skin reaction to it.
Step 1: Ingredients and Supplies
To make these soaps, you need the following:
1 Cup of soap- any white bar you'd like
2 tablespoons warm water
Bowls- 1 for each color you want to make
Molds- I used empty candy trays, but you could use ice cube trays, cookie cutters or even mold them with your hands if you'd like
Fork- for mashing it all together
Step 2: Grate the Soap
Grate your soap on the smaller side of your cheese grater. Since I was making a set each for my niece and nephew, I doubled the amount and grated 2 cups of soap, which was about half of a fairly large bar.
Step 3: Add Water and Mix/Mash
Add 2 tablespoons warm water for each cup of grated soap you have. It won't look like enough at first, but after you begin mixing, you'll notice it start to stiffen up and become thick. I find it easiest to mash the whole thing together with a fork rather than stir. Keep mixing until you have a thick, even consistency throughout and no soap gratings left.
Step 4: Separate and Color
Separate your soap evenly into as many bowls as you have colors to make. Use your food coloring to dye the soap. I started with 2 drops of coloring per bowl, then bumped it up to 4 each for brighter colors. If you're using the same fork to mix all of the colors, start with the lightest color first, wipe the fork off with a damp paper towel after that color is fully mixed, and move on to the next lightest color. This way, any residual coloring you have on the fork won't dirty your next color. Continue until all of your colors are mixed to your liking.
Step 5: Mold and Set
Firmly press your soaps into the molds that you've chosen. Pop them in the freezer for a couple of hours (or overnight) to solidify.
Step 6: Remove From Mold and Draw!
Remove your crayons from the molds. They're now ready to be used in the bathtub, so color away! Or, you know... give them to your kids.
