I have GOT to make one of these...(well, 2 of 'em).

I think I'll try to just put some bends in a glass tube, mount w/ suction cups.

I have a microbalance & RO/DI at work & a moisture balance to cook the water out of some baking soda.

I'll get the indicator for xmas as part of a APA FW master kit... I think I'm set!

If I get good at it, I may buy dry indicator and premix test solutions of differing KH values and start my own ebay business. I'm thinking I can make these for <<$1 ea. (glass, propane will probably be the most costly parts).
