When you burn Hydrogen, the flame is almost entirly colourless. You have probably got some Hydrogen in your house already - it builds up in many central heating systems and needs venting off every now & then (do you have to vent your radiators? - the gas is Hydrogen!). The hydrogen gets there because the warm water reacts (very slowly) with the iron radiators. The iron oxidises into, well, Iron Oxide i guess leaving you with hydrogen.
Rose is the best case tool I've used (and use every day at the moment). But its still shite. Why they don't just bolt VISIO in rather than write their own wierd diagram editors I just do not know. It doesn't exactly say much for UML - hey look you can write a fairly ropey case tool with this method!
