My little brothers and I open a few geodes we bought.
My Lab class and I crack a Geode apart and take a look at the crystals that formed inside it. At 3:04 I use the term condrite when what I meant to say was concretion. Chondrites are a type of stony meteorite containing small mineral granules. A concretion is a a hard solid mass formed by the local accumulation of matter, especially within the body or within a mass of sediment.
