AHA! WITHOUT BORDERS

AHA! What happens if…

Make a guess. Run the experiment. Find out why.

What happens if…? Sometimes the world works quite differently from what you expect. Make a guess, run a hands-on experiment and discover the explanation. Start with a hammer and a feather on the Moon — more mysteries are on their way.

Lunar surface under a starry sky with Earth in the distance

Hammer or feather?

On Earth you probably know the answer. But on the Moon? Make a guess and run the experiment.

Try it

A small wizard figure on a table, a lantern and a huge shadow on the wall

Small figure, giant shadow

Can you make a shadow bigger without the figure growing? Move it and find out what matters.

Underwater scene with a red, a blue and a white plate on a holder and a brass lamp

Where does red go?

Sink colourful objects into the deep. Then switch on a torch. What changes?

Explore

Can two sheets of paper carry the same load?

Same paper, same supports. One sheet stays flat, the other is folded like an accordion. Which one holds more blocks?

Build the bridge

Will a raisin move up in a glass?

A raisin is denser than water, and yet it can float up to the surface. Are a few bubbles enough?

Watch the raisins

Does sugar disappear when you can't see it?

Sugar dissolves in water and vanishes from sight. But does it vanish from the scale? Weigh it.

Weigh and explore

Can paper bloom without watering?

Fold a paper flower, place it on water – and the petals start opening by themselves. How?

Let the flower bloom

Can one line run along both sides?

A strip of paper, half a twist and a bit of tape. Draw a line along the middle and prepare to be surprised.

Make the strip

Experiment · laboratory

I dropped a feather and a hammer at the same time in the lab. The hammer landed first. The feather changed its mind and drifted off to the window.
