Mini Metal Foundry

I built the Grant Thompson mini metal foundry. The metal bucket with the green plastic pale is the foundry.  The plaster and sand mix in the blue surgeons bowl is the lid.  I measured out 5 liters plaster, 5 liters play sand and 2.5 liters water for the foundry.  For the lid, I measured out 3 liters plaster, 3 liters sand, and 1.5 liters water.  I used a peanut can to form the center hole.  I reinforced the lid with a thick piece of wire.
