- Empty Plastic Bottle
- Strips of Paper
HOW TO DO
- Place a strip of paper on top of the bottle. The strip of paper should only stick out a little from the back of the bottle, as shown.
- Next, place some coins on top of the strip of paper.
- Swiftly swipe the paper strip with one stroke of your finger. In case this doesn’t happen, maybe the paper was not positioned properly. Carefully pause the video, study the image, place the paper correctly and try again. Or perhaps your finger movement was hesitant. Swipe confidently and keep trying till it happens.
WHY DOES THIS HAPPEN?
This happens because of inertia. Inertia is the resistance of any physical object to change in its state of motion or rest, or the tendency of an object to resist any change in its motion. The coins do not fall, because of this effect.
Do this experiment with coins and paper. You will find out what happens.
