In this video I crush a naturally occurring glow-in-the-dark rock in my hydraulic press! These rocks are awesome. It is called green calcite and it is phosphorescent which means that it glows in the dark. This mineral is CaCO3 and is in limestone. I talk about phosphorescence and how it occurs when a material absorbs light but then does not re-emit the light for a delayed time afterwards. This is due to forbidden quantum states.

Send me things to crush at:

PO Box 482

North Plains OR 97133

*If you do send me something message me so I know it's coming!

The Action Lab The Action Lab is a channel dedicated to performing exciting experiments and answering questions you never thought to ask! I'll put things in my hydraulic press, vacuum chamber and perform countless other experiments just to watch cool phenomenon. I experiment on the world and objects around me. You'll be so amazed that you'll forget you are even learning anything! Please enjoy as I continually answer the "what would happen if..." questions you have. Feel free to comment with any scientific questions you have about anything. I have made my career as a PhD in Chemical Engineer and now I want to share how awesome science and experimentation can be!
