First you mix it all together, which is Ragnarson's favorite part of any project. I left the food coloring out so that I could make several different colors, but it would be much easier to mix it in at this point for a single color batch. When everything is mixed together you cook it over medium-low heat until it all sticks together. At first I was afraid I had done something wrong because the bottom layer gelled up almost immediately leaving a soupy mess on the top of the pan, but with continued stirring the texture evened out and it all stuck together. I didn't photograph this step because it came together a lot faster than I anticipated and I was afraid to leave the stove to fetch the camera.
I decided to do four colors because there were four colors of food coloring in the package.
I squirted about a dozen drops or so of the food coloring into a small zip top bag and then added the un-dyed dough wad to squish. If you were doing this project with older children I imagine the bag squishing would be a favorite step...we'll look forward to that in the future, eh Ragnarson?
Squish until all the food coloring is absorbed into the clay. The finished wad is then pretty color safe, and it doesn't dye your hands.
I'm storing all the colors together in one bag, since I figured they'd all turn to "sludge" soon enough.
