Slow motion rubber band trick
Put a rubber band in front of a TV screen to see it vibrating in a slow motion. Actually the vibration remain the same but we have the sensation that it slow down. This phenomenon is possible just because the frequency of rubber band's vibration is near the vertical frequency of screen.
The TV screen works as a stroboscopic light and it will not works in front of LCD screen.
