To you, I say: Awesome! There's a lot of cool and random stuff out there, and these are just a few tidbits.


Gallium is a metal which melts on palm of the hand, due to its low melting point (29.76 °C). Submitted by: Karanpal Singh - Amritsar, IndiaTwenty percent of Earth's oxygen is produced by the Amazon forest. Submitted by: Jassim - Salem, India
The noble gas Xenon lasers can cut through materials that are so tough even diamond tipped blades will not cut.Submitted by: Josh Davies - Llanelli, WalesGold and Copper are the only two non-white metals.
The burning sensation we get from chilli peppers is because of a chemical called Capsaicin. Submitted by: Cam - England.The lighter was invented before the match (in 1816 by J.W. Dobereiner). Submitted by: Leah Hopson - Denver, United States
lightningEach time lightning strikes, some Ozone gas is produced, thus strengthening the Ozone Layer in the Earth's atmosphere.Honey does not spoil. Submitted by: Ashalaya - Racine, Wisconsin, United States
pure goldThere's enough gold in the Earth's crust to cover the entire land surface knee-deep.An average adult body contains around 250g (1/2lb) of salt.
The metal with the highest melting point is tungsten, at 3410 degrees Celcius (6170F).One inch (2.5cm) of rain is equal to 10 inches (25cm) of snow.
mosquitoMosquitoes like the scent of estrogen, hence, women get bitten by mosquitoes more often than men do.An ounce of gold can be stretched into a wire 80 kms (50 miles) long.
Natural gas has no odour. The smell is added artificially so that leaks can be detected.Air becomes liquid at about minus 190 degrees Celsius.
Mercury is the only metal that is liquid at room temperature.pure goldAbsolutely pure gold is so soft that it can be moulded with the hands.
Water expands by about 10% as it freezes.It is estimated that a plastic container can resist decomposition for as long as 50,000 years.
If you slowly pour a handful of salt into a totally full glass of water it will not overflow. In fact, the water level will go down.Hydrogen gas is the least dense substance.
Liquid air looks like water with a bluish tint.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%)The only letter not appearing on the Periodic Table is the letter J.
Hydrofluoric acid will dissolve glass.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.
The amount of carbon in the human body is enough to fill about 9,000 'lead' pencils.
