My kids are a little under the weather today, so we decided to
do a low-key project indoors and make bath crayons.
There are tons of tutorials online on how to do this, but I
primarily used this one from Helium.
Here are the supplies you need: White ivory soap, cookie
cutters, a cheese grater and some food coloring. I received the box
of cookie cutters from my good friend Casey as a bridal shower gift - they are
awesome. Not only are there endless cookie possibilities, but they
are perfect for play doh and, well, bath crayons.
You shred the ivory soap with a cheese grater. We ended up using
3 bars of soap.
Then you take a cup of the soap and mix some warm water (about a
1/4 cup) with it. Stir in food coloring of your choice. You are
supposed to stir until it is stiff. I can't say that these every
got stiff. I also read you are supposed to stir until the soap
dissolves, but my kids were a little too excited to wait that long.
Then press them into cookie cutter molds or ice cube trays. I
set these on a piece of wax paper over a cookie sheet. We made
about 12 crayons out of 3 bars of soap in 6 different colors.
We put them in the freezer for about 20 minutes, then popped
them out of the cookie cutters. You are supposed to let them harden
for a day or two before using them in the bath. I'll be interested
to see if they really work - I've read that people have had varying
degrees of success. Either way, the kids had a blast making them,
and it was a very inexpensive project. Let us know if you try it,
and if so, how it works!
