The legendary King Midas turned everything he touched to gold. So what if you actually had the Midas touch?
If we emptied the world's oceans it would reveal 3 million shipwrecks, the world's tallest mountain and the world's biggest canyon. All very cool, but the other side effects wouldn't be.
Catching a falling star, aka a shooting star, is impossible, but let's try anyway.
The Earth, like all planets we know of, is spherical, but there is actually one other shape that could possibly work: a doughnut shape.
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 dust bowl.
We take a Christmas tradition and supersize it as we reveal how to build a gingerbread house that's not only big enough to live in but is also edible - even the electricity.
If you really can't wait for Christmas then there is a solution: you just have to speed up time, which Einstein showed was possible if you were able to travel incredibly fast. Like really mind-bogglingly fast.
Given the nearest black hole would take thousands of years to get to, you don't have to worry about falling into one. We're going to do it anyway, and experience a mind-bending ride where space and time get distorted.
In theory it's possible to build a lift into space. If you took that lift, you could get to space in a few hours. To get weightless, you'd have to stay in that lift for about 5 months!
If you are able to go to Mars on holiday, then you'd need to be prepared for the horrendously long journey, bad weather, and lack of facilities. If you can cope with all that, there are some very special places to see!
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.
We can see them twinkling away, but what if you wanted to actually visit one of the stars in the night sky? You'd be in for a long long journey!
They might look all nice and fluffy but clouds are not, despite appearances, made of cotton wool.
From putting mirrors into space, to planting a trillion trees, there are many suggestions for stopping climate change. The good news is some of the easier ones would actually work!
It would be the ultimate house move: packing up and setting up home on the Moon nearly 400,000km away. The good news is that there is water on the Moon, along with everything you'd need to build a house.
Teleportation might actually be possible in theory but it would be rather dangerous. What they don't tell you in science fiction is that the speed you'd come out of the teleport depends on where you went.
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.
What would happen if you could put yourself in slow motion? Well as the rest of the world raced on, you'd witness extraordinary events that are normally too slow to see.
