Diatomaceous earth is just not as interesting after 10 bong hits...
Side note, a coworker collected a sample of this stuff on a site we were drilling south of the Bay Area for geotechnical investigation. It looks and feels like a super fine sand or coarse silt. The big surprise comes when you try to pound a proctor curve on it. The curve just keeps rising on the moisture side and doesn’t break over until it’s crazy high, like 50+% water. It’s because the diatoms are little spikey glass spheres that fill up internally too.
I use Food Grade DE in my smoothies sometimes. :)
