AMAZING SCIENCE FACTS\

1. Raindrops are not shaped like a teardrop (as they are almost always depicted in drawings) – they are actually spherical.
2.When you hold a shell to your ear to hear the sea, the sound you hear is actually your own blood rushing through your veins! You can use any cup shaped object to hear this effect.
3. When you are alive, your brain is pink. When you die, it turns grey. While we describe the brain as “gray matter” and “white matter”, this is not a true description of its color.
4.Dolphins don’t drink water – if they drank sea water it would make them ill and potentially kill them. They get all of their liquid needs through the foods they eat.
5.Plastic bags are better than paper bags for the environment. The manufacturing process that makes paper bags requires far more energy than that which produces plastic. Recycling paper bags takes more energy than recycling plastic, and paper bags take up more space in a landfill. Because landfills are usually airtight beneath the surface, paper and plastic are equally bad at biodegrading.
