___Cost so far, $10 US. I have the mylar (survival blanket) & plenty of corrugated stock from moving boxes. I almost bought a thermometer, but I think I can use our cooking one. While I wrok on the reflector & after the paint dries on the tube, I have in mind to stuff the tube with debris & see what goes with it in the Sun sans reflector.

Ok,
So you paint the metal pipe.
Wrap it in mylar (emergency blanket) - on the outside?
Then stuff the debris inside.
And let it bake...? How long does it take - to bake?
how hot does it need to get?
I should probably re-read the links, but asking you is easier...
