Do any of you have experience with bottle-size compost experiments?
I'm interested in doing something like the following
http://www.bottlebiology.org/investigations/decomp_main.html
This would be part of my worm talk at local schools and I'd leave the bottles for a few weeks then return to talk to the kids about their observations.
These little microcosms look very interesting, but I don't want to introduce something that others have found difficult.
Thanks!
Mark
