Why do some volcanoes erupt with spectacular lava fountains while others release lava more quietly? Scientists have discovered that a hidden effect of extreme heat inside magma may help explain the difference. Experiments revealed that superheated magma can delay crystal formation for more than eight hours, compared with just 20 minutes in magma that has not been superheated.
