Check Ebay, there's a lot of glass carboys listed there but most aren't cheapAny idea where he got that glass from?

It’s a shame there’s not (I’m assuming) an induction powered pump.
12v whale pump on the way?I've been looking at what I have 'in stock' - they are all a bit more powerful than I want - 12v jobs. The things we are concerned about are voltage (DC for safety), flow rate, and head. One pump I was going to use was fine for flow rate but only quoted a 300mm head so wouldn't reach the top of my 500mm jar. I think we only need about 500ml per minute at most but maybe could throttle a higher flow rate one electrically or physically.
I've sent off for a cheap, small, submersible one (arriving tomorrow); I'll let you know how I get on with it.
Good thinking about the induction pump @Stew - I'm going to look into that. Should be feasible to drive a pump with magnets through thin glass!![]()

OK, results of experiment 1 - my little pump will lift a nice flow of water the 500mm that I need running off a 5v USB charger PSU.
Now a) decide if I'm drilling the jar, b) start building the 'rock face' outside the jar with the aim of sliding it in when finished
I think I have a plan!
I have found a container that should be perfect and possibly one that’ll be acceptable in the house (maybe!)
