Crazy crane

How do you do the exhibit?

Grab the ropes at the side of the table and pull. Can you get the cargo off the quay onto the ship? Or from the ship back onto the quay?

What's the science behind it?

Harder than it looks, huh! So the ropes are connected two by two.

You need technical insight to solve a problem like this. Technical insight is actually a combination of thinking carefully and understanding how things work or are put together. So think carefully and test some things. Ask yourself questions: how to move the load up and down? How from front to back? And how from left to right?

Technical insight in cycling

When you see a bicycle and understand that the pedals make the chain turn, and that this makes the wheels move, you are using technical insight.
