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.

If you are locked in a completely sealed room, you will die of carbon dioxide (CO2) poisoning before you will die of oxygen (O2) deprivation.

If you put a raisin in a champagne bottle, it will rise and fall continuously.

The element Californium is often called the most expensive substance in the world (as much as $68 million for one gram.)

Gold and Copper are the only two non-

white metals.

The element Copper (Cu)

The element Gold (Au)

The only letter not appearing on the Periodic Table is the letter “J”.

The burning sensation we get from chilli peppers is because of a chemical called Capsaicin.

Unlike any other element, helium does not solidify.

Liquid Helium

Gaseous Helium

Plasma Helium

Astatine is the rarest element within the Earth’s entire crust.

Twenty percent of Earth's oxygen (O2) is produced by the Amazon

forest.

Each time lightning strikes, some Ozone gas is produced, thus strengthening the Ozone Layer in the Earth's atmosphere.

A rubber tire is actually one single giant molecule.

A bucket full of water contains more atoms (H2O = 3 atoms) than there are bucketfuls of water in the Atlantic Ocean.

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.)

Hot water freezes faster than cold water (the Mpemba effect.)

The five states of matter are: Plasmas, Gases, Liquids, Solids and Bose-Einstein Condensates.

The coldest state of matter — Bose-Einstein Condensate superfluid — defies gravity and instead of flowing down, it flows upward.

Hydrogen is the most abundant element in the Universe (75%).

Oxygen is the most abundant element in the Earth's crust, waters, and atmosphere (about 49.5%)

There's enough gold in the Earth's crust to cover the entire land surface knee-deep.

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) .

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.
