Re: Where does inflated value go?

Sounds like (if I'm understanding that correctly) my suspicion was right, and the inflated value goes to those who were given the newly-printed money, the banks.

Re: Copper in vacuum thermos

The patent describes experiments. They say a bottle with plating (nickel and silver in their case) drops from 90 C to 55 C in 24 hours, and a bottle without plating to 47 C. That significant, though not revolutionary. Not the most reliable source, but the patent doesn't smell like woo, at least. Man...

Re: Multipath Crazy Straw

The fact that you can hold water in a straw by covering only the top end tells me surface tension is doing something important.
