There are at least eight lakes on Earth that are naturally pink in colour: Lake Retba in Senegal is one such lake that is nearly 40% salt. The Hutt Lagoon, Pink Lake, Lake Hiller and Quairading Pink Lake are lakes in Australia. These lakes are pink in colour because of a certain algae that breed only in salt water.

You can’t actually sink in the Dead Sea: The Dead sea is a stretch of water around 80 km long and 18 km wide, with a salt saturation rate of 34.2%. This makes it 9.6 times saltier than the ocean. In fact, it is called the dead sea because no marine life can survive in such saline water. However, all the salt makes this sea denser, than the human body, allowing you to float without any assistance.

The acid in our stomach our stomach is strong enough to dissolve zinc: That is because our stomach walls generate cells so quickly that by the time one layer gets dissolved, another layer is ready to take its place. We need the acid to help break down our food so that digestion is easier.

Human Hair is almost impossible to destroy: Hair is like the superman of the body! Apart from burning it, there are actually very few things that can destroy it. Hair decays extreme slowly. In fact, it decays so slowly that some Egyptian mummies dating back to thousands of years still have hairs on their heads. The only real weakness that hair has is fire as it is made up of 50% of carbon.
