EP22  You Had Kangaroo Legs?
Oct. 05,2022

EP19  You Only Ate Burgers?
Sep. 30,2022

If everyone in the world ate nothing but cheeseburgers, we would run out of land, and even if we went meat-free, we would have to invent some crazy burgers to get the nutrients we need.

EP18  There Were No Colours?
Sep. 29,2022

EP17  You Flew Like a Superhero?
Sep. 28,2022
You Flew Like a Superhero?

Flying like a superhero may sound like enormous fun, but there are some serious downsides that Hollywood does not tell you about - weather, extreme cold and even fizzy blood.

EP16  Money Grew on Trees?
Sep. 27,2022
Money Grew on Trees?

If you had a tree that could grow money, would that make you rich? Even if you wait 20 years for your tree to grow, you will probably end up no richer than you started.

EP15  You Shrunk the Earth?
Sep. 26,2022

EP11  Animals Were Supersized?
Sep. 20,2022
Animals Were Supersized?

We look at whether some animals can get gigantic and find out that if you are being chased by a giant snail or a humungous butterfly, then fear not, you must be dreaming.

EP10  Your Mind Could Move Things?
Sep. 19,2022
Your Mind Could Move Things?

We imagine a world where it's possible to move things with your mind like films, but find that the laws of physics mean that this superpower wouldn't quite work like you expect.

EP6  You Lived on Venus?
Sep. 13,2022

Venus has acid rain, crushing pressure and is hotter than an oven, so it might not sound like the ideal place to live. However, up in the clouds it's almost just like home.

EP5  You Could Stop Global Warming?
Sep. 12,2022
You Could Stop Global Warming?

Imagine if we had a thermostat that could turn the world temperature down - could we fix global warming? But be careful, a few degrees too far and could cause an ice age.

From cloning to 3D printing, what if we could actually make copies of ourselves?

EP3  We Got Rid of Bugs?

EP2  You Walked Through Walls?
Sep. 06,2022
You Walked Through Walls?

Wouldn't it be cool to be able to walk through walls? From turning into a gas to quantum trickery, we discover why it wouldn't be quite as useful as you'd like.
