Urine as a Fertilizer

concentrations in urine samples were low compared with other organic fertilizers, but copper, mercury, nickel and zinc were 10–500 times higher in urine than in precipitation and surface waters.

The World’s First Lamp

Erik’s link to the orange lamp on Saturday reminded me to post this. This is Project #1 in Making It, and we often open our lectures by building one of these, but I realize I’ve never talked about oil lamps here on the blog. Forgive the somewhat atmospheric photo.

Cat Poop Compost Installment #2

...g to move it along faster, I did what I’d do for any compost pile that was a little pokey: I turned it, and added nitrogen and water.* Shoveling 50 gallons of kitty litter is exactly what I want to be doing on any given Saturday! As I shoveled, I decided that if I didn’t already have Mad Kitty Disease, I’d have it by the end of the day.
