We all know that the elephants have a strong skin. But the amazing thing is, a small Leech teeth are strong enough to cut though elephant skin. Leech teeth leave a characteristic triangular incision that can cut through any tuff skin.
Super Glue was invented by accident. The researcher was trying to make optical coating materials, and would test their properties by putting them between two prisms and shining light through them.

do you know the amount of heat generated by our body due to body functions? In 30 minutes, the average body gives off enough heat to boil a half gallon ( about 2 liters) of water.
Pressure increases 1 atmosphere for every 10 meters, so a deep sea organism can experience a range of pressures from 20 atmospheres at the shallowest point to 1100 atmospheres in the deepest.
