Comment on Drinking coffee from a cup made of coffee
sga@piefed.social 1 week agowhile true, they are effectively single use (in latter half of video, he slices open a cup, and shows cracks developing). these are, in theory, replacements for platic temporary cups. and the coffee grounds are essentially just a binder used in agar mix to harden it (kinda like adding wodden chips in some glue mix to make it hard).

Oh, yes. I forgot about the agar. Is this the same thing that’s used as a food for bacteria in a petri dish?

yesnt. agar is not exactly the food (it is one part of the food). we usually add other nutrients as well. consider agar like a staple bread (povides structure).
