What you need to prepare
- Glass with thin straight walls.
- A small mirror.
- Sticky tape.
Attach tape the glass to the front side of the mirror. Pour to the top of the water. Hasten the face to the glass and look through it in the mirror.
You will see reduced its head.
Slope head to one side - head in the glass will bend completely to another. If you blink right eye, the head will blink too right, not left, as we are accustomed to see in an ordinary mirror.
Now you see your real image, unlike a mirror, which turns from left to right.
