– Mrs. Rubert’s students, Foothill Knolls STEM Academy of Innovation, Upland, Calif.

Glass: How is it made?

Dr. Universe: How is glass made? And, what is it made out of? What about thick glass like they are putting up on the Space Needle? – Tali, almost 8 years old, Seattle, Wash.

Dear Tali,

We can make glass in factories and we can find it in nature. Some volcanoes make glass. When they spew out lava, it often cools into obsidian, a black glass. Glass can also form on sandy beaches. Small tubes with smooth glass on the inside may appear after super-hot lightning strikes the sand. » More …

By Bailey Campbell

Why do dogs and cats fight? – Kari, 10, Essex
