Silica Experiment
If you want to see some real silica, go to the beach or to a playground with a sandbox. Beach sand is nearly all silica (actually molecules of silicon and oxygen). Notice how easy it is to get wet sand to stick together - that's the beginning of the formation of sandstone. Look at sand through a magnifying glass to see how the little grains of sand look like glass - because glass is made out of sand (in fact, the magnifying glass itself is made from sand).
