There is a theoretical limit for how fast humans can run but let's ignore that and imagine we could outrun even the fastest vehicles on earth. However there is a problem - we'd have to keep stopping to eat and cool down.

They might look all nice and fluffy but clouds are not, despite appearances, made of cotton wool. But let's say they were… then, yes, you could actually sleep on one but they'd now weigh as much as 30 million hippos!

The legendary King Midas turned everything he touched to gold. So what if you actually had the Midas touch? Well you'd get rich for sure but food would be inedible and your house would collapse under it's own weight.

3.0 6 x
It's easy to take some things for granted. Like the earth spinning. If it stopped spinning, days would become a year long, it would get unbearably hot and the sea would be replaced by a windy dustbowl.

In theory it's possible to build a lift into space - but if you took that lift: while you could get to space in a few hours, if you wanted to get weightless you'd have to stay in that lift for about 5 months!

4.0 1 x
If a human wants to fly like a bird then they have 3 options: flap their arms 10,000 times a second, build a pair of massive wings or, fly to Titan - a moon around Saturn where gravity is low and the atmosphere is thick.

4.0 8 x
The moon may look a bit like a piece of cheese but if it was then it actually wouldn't stay cheese for long. The cheese would separate with water and gases boiling up to the surface to create oceans and an atmosphere.

4.0 13 x
Catching a falling star - aka a shooting star - is impossible, but let's try anyway. As we push bigger and bigger space rocks down to Earth we'll see why trying to catch a falling star would make our world look like Saturn!

Season 1, Episode 17 - The Earth Was Shaped Like A Doughnut?

3.0 8 x
The Earth, like all planets we know of, is spherical but there is actually one other shape that could possibly work - a doughnut shape. Days would only be 2 hours long but in the middle you could see technicolour sunsets.

3.0 10 x
In this episode we flatten the earth like a pancake to find out just how bonkers a flat earth would be. Gravity would be completely different with everything pulled towards the centre.
