    Last chemistry I took was in 1966, so that is why I am asking how it is made, or why it does that.

    Memory foam pillows will freeze stiff as a board if exposed to the right cold temperature. You don't want to get whacked with one in a pillow fight, even warm, as they weigh quite a bit. I just made a trip to northern Utah and had one in a box in the back of my truck, and it got STIFF. So there must be some captive water molecules involved. Anybody know how they are made?

    Solder, made up of lead and tin, has a lower melting point than either lead or tin.
