If you made a few of them out of translucent yarn, then put a sealed transparent plastic bag with water and different coloured food dye in each, I reckon you'd have a great little start to a crafty mad science lab.

I know you can get plastic yarn (looks like the sheathing from wires), but can you get translucent stuff?
