Food coloring can get expensive using a lot of it, so I started using kool-aid in its place. Well it has worked great and has brought a lot of fun to our play.
There are so many ways you can use kool-aid. I have gathered a list of things we have done and over time there will be more to add, so be sure to check back.
Also, kool-aid is $.20. What better way to have fun then to add a little scent to your play.
