I have put the pices in this sort of “floating devices” made with straw and tape. I hope they hold. Now I am trying an already used ferric chloride I had in a bottle, which I dunno if will work at all. I have set several of them on top of eachother on a plastic bottle bottom (two of them, the ones I didn’t put, don’t fit in this container).

Edit, later:

The liquid works very well. I didn’t even add any water to refresh it. I have put the pices out now because it is getting late and we have to eat, but I will continue tomorrow. The floating devices held prety well too, with minor retouching to some as the tape got wet. I think scotch tape would work better (tried it on one of them).
