How to make a card float in mid air :

In order to perform this Floating Card science experiment all you need is a cotton spool, thumbtack and a postcard. First of all cut the postcard into half and then through the center of this halved postcard stick a thumbtack. Now take a cotton spool and place it over the pin of this thumbtack. Hold this postcard with cotton spool and blow air down the hole of cotton spool. While blowing air through the cotton spool remove your hand from the postcard.

You will be amazed to see that the postcard does not fall and instead it remains there hovering below this cotton spool. This happens because a low air pressure is produced when you blow air through the spool. The normal air pressure then makes the postcard hover below the spool by applying pressure from below the postcard.

You may have noticed that this Floating Card science experiment is pretty simple to conduct and does not require much effort at all. Kids can try this science experiment at their home and show it to their friends or family members. They can even use this Floating Card science experiment for their school project or science fair.
