Top 10 fun science facts for kids
April 3, 2018

To celebrate the launch of our super science book for blind children, Science Experiments, we’ve put together a list of 10 mind-boggling science facts to wow your friends or schoolmates!

Freddie, age 13, tries out some science experiments at the Science Museum Wonder Lab chemistry bar.

  1. Custard is a non-Newtonian fluid – means it doesn’t follow the normal rules of liquids: sometimes it has properties and sometimes it has properties like a solid. Did you know that if you filled a swimming pool with custard, it would be possible for a person to run across it without sinking!
  2. Ketchup and some other sauces are also a type of Non-Newtonian fluids called ‘shear thinning’ liquids. This is why they stay almost solid in the bottom of a plastic bottle, but if it is squeezed the sauce pours out easily.
  3. One million Earths could fit inside the sun – and the sun is considered an average-sized star.
  4. The Bucyrus RH400, owned by Caterpillar is the world’s biggest hydraulic excavator. Used for mining, it has a front-shovel excavator weighing approximately 889t – that’s nearly the same as 150 African elephants! And it stands 45ft tall – about the size of 2 average houses on top of one another.
  5. The word “hydraulics” comes from the Greek word hydraulikos, which in turn comes from the world for water and pipe.
  6. When the Indonesia Krakatoa volcanic eruption in 1883 was so loud it ruptured eardrums of people 40 miles away, travelled around the world four times, and was clearly heard 3,000 miles away!
  7. Ships float higher in seawater than in fresh water because salt makes the seawater denser.
  8. The longest ship ever built is Mont (also known as Knock Nevis, Jahre Viking, Happy Giant, Seawise Giant), which during its use as oil ULCC (Ultra Large Crude Carriers) supertanker was the largest moving man-made object on the planet. It was 458.45m (1,504 ft) from stern to bow making it longer than the Empire State Building’s height.
  9. Temperatures in a lightning bolt can hit 50,000°F or 27,760°C!
  10. You wouldn’t be able to walk on Jupiter, Saturn, Uranus or Neptune because they have no solid surface.

Do you have a fascinating fact that’s not on the list? Let us know what it is and we’ll post it on social media. Email or get in touch via Twitter or Facebook.
