💡 Did you know?
Some woods glow under UV light—and some don't!
The bowl on the left is made from honey locust, while the bowl on the right is made from American beech. When we shine a UV flashlight on them, the honey locust lights up, but the beech stays dark.
This glowing effect is called fluorescence. It happens because every wood species contains different natural compounds, called extractives. Honey locust has extractives that react to UV light and create that glow, while beech does not.
It's a great reminder that wood is more than just wood! Each species has its own unique characteristics and surprises.
Want to learn more about what makes different woods unique? That's exactly the kind of hands-on discovery students make in the Wood Science program at Northcentral Technical College.
Science, craftsmanship, and a little bit of wonder; all hidden inside a piece of wood. 🌳
