Fountain On Fingertip | Gujarati

Date: 2016-02-17

This is a fun experiment. Take a small transparent plastic bottle. Make a small hole in its base. Make a big hole in its lid and press fit a dropper tube in it. The orifice of the dropper tube should go in. Now shut the base hole and push the bottle in a big jar of water. On opening the base hole water will gush out of the orifice like a fountain. This is because the pressure on the lid of the bottle is greater than that at the orifice. On closing the base hole of the bottle the fountain will stop.
