Water expands by about 10% as it freezes. (Which is why the less-dense solid form of water – ice; floats in a glass of the more dense liquid form of water.)

An ounce of gold can be stretched into a wire 80 kms (50 miles) long. (West side of St. Louis to Staunton, IL)

Absolutely pure gold (with all other impurities removed) is so soft that it can be molded with the hands.

An average adult body contains around 250g (1/2lb) of salt (NaCl = sodium chloride) .
![Page 25: A bee sting is acidic and a wasp sting is alkali. To treat a sting by one of these you should use the opposite type of chemical.](https://reader035.fdocuments.net/reader035/viewer/2022062519/5697bffa1a28abf838cc0716/html5/thumbnails/25.jpg)
The amount of carbon in the human body is enough to fill about 9,000 'lead' pencils. (BTW – the “lead” in “lead pencils” is really one of three allotropic forms of carbon --- it is “sheeted”– and in not lead at all!)

If you slowly pour a handful of salt (NaCl) into a totally full glass of water it will not overflow. In fact, the water level will go down.

Natural gas has no odor. The smell (2% tear gas) is added artificially so that leaks can be detected.
