Zoetrope

How do you do the exhibit?

Spin the drum. Look through the slots. What do you see?

What's the science behind it?

Did you know that there is a membrane in your eyes? We call that membrane the ‘retina’. When you look at something, that image is projected onto the retina. Next the image is sent to your brain. And that's how we can see!

This drum is a zoetrope. If you spin it really fast and look closely through the slots, you will see an image of one of the figures through each slot. Each figure is slightly different. You see the images in such quick succession that your brain makes them flow together... until you just see a moving image.

Moving images on TV

The fact that you don't always see each picture separately is quite handy. This allows you to watch TV, for example! On TV, a lot of still images come in quick succession. If they look alike, our brain makes them flow together and we see a moving picture.
