Summary

Glass is a magic thing that is both solid as a wall and clear as the air. It starts out as sand and with tons of heat, and a few key ingredients, it becomes the super useful material we know and love. In this episode we look at how glass is made, why it's clear and how nature makes glass too. Plus, hear about Sanden's latest invention and guess the all new Mystery Sound.
