Crush Lava Hydraulic Press
In nature, nearly all lava of the Earth’s crust consists of silicate minerals, like pyroxenes, amphiboles, micas and quartz, while rare nonsilicate lavas can also form by local melting of non-silicate mineral deposits. However, lava can also be made in the lab in the form of molten copper and aluminum, but this substance is slightly thinner than the material spewed from active volcanoes. Read more for a short video.



As the hydraulic press slowly presses down on the melted rock, it rips open underneath the pressure and flames erupt onto the sides. The fire gets stronger as the lava is crushed, and at the end, it’s almost as flat as a pancake. Despite looking cool, the hardened lava is still not safe to touch without proper safety equipment, as it would still cause room temperature water to boil.
