Approx. 1mL of strontium carbonate, 1mL of sulfur, about 1mL sodium nitrate, 1mL of sugar and about 0.01mL of manganese carbonate was ground together and placed on top of a piece of chalcedony. It was ignited with a match and immediately burst into bright yellow flame which burned for a couple of seconds. This resulted in a hard grey melted substance that was quite luminescent.
This mixture was named "Gorn Powder" in reference to a Star Trek episode wherein an alien (the Gorn) was defeated using a mixture of a nitrate, sulfur and carbon (aka "black powder").

This is a land art "doodle" I did the other night. Land art doodles are quick, fun and they can lead to great ideas for bigger projects. (this one gave me some ideas, I'm hoping I can show you soon if I can find the time) I got the doodle idea from a contact that does some of the best doodles I've seen.
I didn't want to spend to much time in the cold the other night but I did want to do some land art with the snow we just got so I thought a doodle would be perfect. The snow was very powdery and it wouldn't pack together so I found a stick and started drawing in the snow. If I used the stick like a pencil it would make little piles of snow so I used a pointillism technique to minimize it.The pattern reminds me of coral.

Evins Reindeer Moss (a.k.a. Powder-puff Lichen, Oak Toes Lichen; Cladonia evansii ) - Duke Island Road, Tiger Bay State Forest, Volusia County, Florida
I'd expect to find Reindeer Moss Closer to Christmas, Florida
but there it was at Tiger Bay.
Go figure.
I have a bad habit of forgetting to whipe off the table after spilling my protein powder. My wife loves that about me.... =)
Loved these little purple flowers, but will have to wait on Nancy for an ID. For now they're simply purple powder puffs. Finally slept past 6 this morning so slowly getting into summer mode.
Perennial Geranium is the ID. Thanks, Nancy!
