Volcano Tank (Smithsonian)

Bring earth science to life with the Smithsonian Volcano Tank, an immersive desktop experiment that demonstrates the power and beauty of volcanic eruptions. Simply fill the clear tank with water, add eruption powder, and turn on the built-in LED lighting system to activate a dramatic bubbling eruption effect. The swirling “lava” and shifting colors create a realistic volcanic plume contained safely inside the aquarium-style tank.
