The planet Saturn has a density lower than water. So, if placed in water it would float.
Blood and cells contain an enzyme called catalase. Since a cut or scrape contains both blood and damaged cells, there’s lots of catalase floating around. When the catalase comes in contact with hydrogen peroxide, it breaks H2O2 into water and oxygen gas. The oxygen gas forms the bubbles.
Why does hydrogen peroxide foam when you put it on a cut? No foam, when it is spilled on the skin.
A typical hurricane produces the energy equivalent of 8,000 one megaton bombs.
In a gas cooker there is absolute combustion with blue flame. Gas completely reacts with O2 and converts to CO2 and H2O gas. But in a wooden hearth partial combustion takes place and in addition to CO2, H2O, Unburned C molecules are in the flame resulting a yellow flame.
Why the flames of a wooden hearth are yellow and the flames of a gas cooker are blue?
The low frequency call of the humpback whale is the loudest noise made by a living creature.
Without its lining of mucus your stomach would digest itself.
The Earth spins at 1,000 mph but it travels through space at an incredible 67,000 mph.
Normally K2CO3 (potassium carbonate) is the main contents of ash. Lime juice has Citric Acid. When mixed these 2 compounds suddenly start an acid-base reaction. K2CO3 is a week base and Citric acid is a week acid. As a result of this acid-base reaction CO2 gas emitted from the mixture.
Why some kind of gas comes out when we add lime juice in to ash?
Our eyes are always the same size from birth, but our nose and ears never stop growing.
The brain uses more than 25% of the oxygen used by the human body.
On a clear day, a beam of sunlight can be reflected off a mirror and seen up to 40km away.
The reason for the telephone wires to sag on a hot day is because of thermal expansion of the copper wiring. The atoms of the wire, vibrates faster, due to the higher temperature.
Why do telephone wires sag during noon on a hot day?
Do you know that an ostrich’s eye is bigger than its brain? Also the pupil of an octopus’ eye is rectangular.
A neutron star is the strongest magnet in the universe.
Most elements are metals and most metals are silver-colour or gray. The only non-silver colour metals are gold and copper.
The ship has a streamlined and hollow shape which causes it to displace more water than its own weight. The iron nail does not have a hollow shape to displace more water than its weight. So it floats.
