Hey folks,

Hey folks,
If you are into extreme plumbing, then you could plumb them together and pump coloured liquids through them. I've seen a couple of designs where with careful selection of liquids then you can alternate colours as they are pumped around the system, then have them separate back out again on the return flow. You can end up with an organic lava lamp sort of effect if done right. (or probably a complete mess if done wrong...)
