- 1 C flour
- 2 C oatmeal
- 1 C water
- 1/4 C instant coffee added into the water (this is approximate. It’s been long enough that I don’t remember how much I used)
Mix oatmeal, flour and coffee together. Gradually add water to mix. Knead. If mixture is not dark enough, you can add more instant coffee. It will help change color and give brown flakes in your dough. You can also add cornmeal to the mix if you want more ‘texture’, but I felt this was pretty textured enough.
We then took chunks of the dough, flattened it out, and molded it onto the cone. The boys then took green playdough and molded it into clumps of trees and added it for emphasis. We also grabbed some rocks and put them in, as well.
Typical mixture of baking soda and vinegar (mixed with a bit of red food coloring) allowed us a general idea of the burst and flow, without a big mess. We toyed with the idea of a modified Mentos & Diet Coke explosion, but I didn’t want to rebuild the volcano with the needed pressure mechanism. It would’ve been way cool, though!
