(Tin foil has been hard to come by this many a long decade. What the worlds coming to I know not. It's even been hard to buy tin plate for almost as long. Cut so nicely it did. Sciissors you could use at a pinch. Once only maybe. Soldered so beautifully it did. Good for boxes and shields and even heat "sinks". Sure I am you can buy iy here too but where may be difficult when one kows one to be in Pune Kharadi but not where Kharadi is. Yesterday I found it to not be where I'd thought. Googgle maps ignored Occam and multiplied alternatives so the place I was measuring map distances from was not were I was. All good fun. I've not made any foil hats yet but that may happen tomorrowish. As an adjunct to the solar box cooker. anon Russell A Rose by any other name Wood ... ? Groan.
