Artist Bob Wysocki plays around with homemade lava to create cool experiments that mesh sculpture and geology. Here, he makes a mini shield volcano.
Here's a class with a great title:
As part of the honors course "The Art and Science of Lava" the attempt was made to form a shield volcano – Mauna Loa, Kilauea, etc. – by pouring in a "J" shape tube with the lava slowly emerging upward, overflowing, pooling, growing outward, etc. This was the fourth attempt, a success in terms of uniformity and effusion rate.
