But the warm weather is back, so we've been out fooling around with metal. Hugh has made a very nice candle-holder and is working on version 2.0. Christopher is making a mailbox-train (Christopher likes trains...) and Mr. Dave, well... Mr. Dave decided to make a hydrogen torch! I'm a little unclear on exactly how it works, but it works! Something about the pressure of water & using electricity to separate the hydrogen from the oxygen. Very cool...
