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, India | Twenty 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, Wales | Gold 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 |
Each 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 |
There'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. |
Mosquitoes 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. | Absolutely 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. |
