Fun experiments include burying a to-go cup. The worms will eat all the paper off the thin plastic liner. The thin plastic liner is one meant to be broken down at a professional composting site and you can see it at the bottom of the photo below. I feel like in less than three weeks time my worms did pretty well! I put it back for them to break down the rest.
This week was one of my first big harvests of compost sans students. I was surprised at the number of stickers I ended up with. They eat all the banana bits, the avacado bits etc. (I think those are the only things that go in with a peel.) and all that’s left is the sticker.
