An Opalized Pine Cone
This is very cool. A fossilized pine cone where the gemstone opal has replaced the organic material. “This beautiful specimen was found at… “Kens Retreat” in the Coocoran mining area N/West of Lightning Ridge…” in Australia of course.

Sugru
One of my favorite new products in the last couple of years is Sugru, a moldable silicone rubber compound. I mentioned it in one of my classes today so I thought I’d link to their rather irreverent video explaining their product. It’s a bit pricey, but invaluable for fixing A LOT of stuff.
