Mission 21 : Use water to cool down molten materials.

As you got some water in the previous missions, we'll use it now to cool down molten materials.

First, make some molten metal in your Melting Furnace.

Then, select the water you collected and use your constructor/destructor to put it on the molten metal cubes.

The molten metal will cool down instantaneously and you'll save valuable time.

In a future mission, we'll see how to automate cooling of the molten metal alloy.
