Make pizza with a plasma cutter, a backhoe and a pile of mud!

Step 10 Mudballing

We covered the sandcastle with a layer of damp newspaper as a separation layer.

Then I mixed up a power of mud by doing the mud dance.

Then I stacked mud balls all around the sandcastle, smooshing each one against the ones below.

This layer is the oven dome, which holds heat and radiates it down from above.
