#TryThisTuesday: Cork Balancing

Today we’re challenging you to balance a cork on its round side, on the very end of your finger, whilst keeping your finger straight.¬†20161018_163129_resized

Could you manage it?

It’s quite tricky, but here’s a hint: two forks could help you out.

Have you figured it out yet? Remember the cork must be balanced on your finger not the forks.

The solution is to stick the forks into either side of the cork. You should then be able to easily balance it on the end of your finger.

There are two reasons this works. Firstly the forks add weight to the object you’re trying to balance. Because the ends of the forks hang below your finger, it lowers the centre of mass so that it sits underneath your finger, increasing the stability.

Secondly, adding the forks extends the object. By making it longer, the centre point is also stretched making it easier to locate so easier to balance the object. This is why tight-rope walkers often have long poles to help them balance.
