Answers coming up below, but first here's a festive activity that will enable you to show off to your mates!


SIR ISAAC NEWTON'S SHOW-OFF INERTIA DEMO ACTIVITY

What you'll need:

1 coin - metal ones (or even chocolate ones - if you're lucky!)
1 elbow

What to do:

Bend your right arm with the elbow pointing at your attentive audience (use your left arm if you're left-handed). The upper part of your arm needs to be parallel to the floor, with the palm of your hand facing upwards next to your chin. Balance a coin on the flat part of your arm next to the elbow. Explain to your lovely audience that you are going to catch the coin in your hand, which wouldn't be much of a trick, except that you will miraculously catch the coin with your RIGHT hand (or left hand if that's the one you're holding in the air!).

In one very sudden, very quick move, drop your arm. This will cause your hand to snap forward, so your hand ends up in the place where your elbow started off, while your elbow falls away from under the coin. As your hand touches the coin, close your fingers around it to catch it.

(You might need a bit of practice, but once you've mastered it, you'll catch the coin every time!)


The science bit:

Since the coin is still, it has inertia, which means it tends to remain in the same position. When you move your elbow very quickly, it just drops out from under the coin. This leaves the coin hanging momentarily in the air. Gravity pulls the coin towards the ground, but inertia gives it a slow start. Your hand is moving quickly so it catches the coin before it falls to the ground.

Tip for Experts:

Once you've mastered the art of catching one coin, try using more than one. Stack the second coin on top of the first, and try to catch the two coins together. Then work up to three, four or five coins for a really impressive trick to show off over Christmas dinner!

That's all from Planet Science News this year, but there's plenty more to explore and discover on www.planet-science.com.

We've said farewell to the lovely autumnal moon previously decorating the home page and welcomed in the new winter look, groovy speed skaters in their high tech gear. (By the way, there's an e-card waiting for you too - just click through where it says Season's Greetings.
