Cummingtonite
 

Here's today's science lesson.....

Cummingtonite or magnesium iron silicate hydroxide is a metamorphic index mineral with the chemical composition (Mg,Fe)7Si8O22(OH)2. It is a member of the cummingtonite-grunerite solid solution series which ranges from Fe2Mg5Si8O22(OH)2 for cummingtonite to the iron rich grunerite endmember Fe7Si8O22(OH)2. Manganese also substitutes for iron producing a manganese rich variety. The cummingtonite series is polymorphic with the anthophyllite-gedrite series and often requires optical or X-ray diffraction analysis to distinguish the polymorphs.

haha thats awesome, thanks for the info. thats something to share at a party for sure :P

And here I thought it was something sexual. :D

I was fucking this bird last night, I was pounding away and she was almost cumming but couldn't quite go over the edge. So I said, "I'm gonna cum baby!" and started screwing up my face like I was going to cum, then she arched her back and came and came and started screaming, and her tight little pussy milked the cum out of my cock and into her wet snatch. It was awesome.
