Water Bottle Fountain Experiment

This experiment has lots of variations and many different ways of building depending upon time and resources.

Water bottle fountain experiment.

Fill a small bowl with cold tap water food colouring is optional but makes a much prettier fountain. Add the funnel to your bottle and carefully pour your water into the bottle. Science behind this science project. If the bottle is wet the blu tac will be hard to stick.

If you make one why not film it and upload it to youtube you never know. Once the water drops below the level of the outlet tube in the fountain supply the heron fountain will stop. When you invert the water bottle then plain water of the bottle starts to flow out from drainage straw due to gravity and air pressure decreases inside the bottle. You ll notice that water will rise up through the straw to the same height as the water inside the bottle.

Wear a thick glove or oven mitt to handle the bottle. Now to make the water bottle fountain carefully with a pen poke a hole in the empty bottle just big enough for a straw to poke through and seal with blue tac. This is the hardest part of the activity and is best done by an adult. This is due to equal air pressure pushing downwards through the opening of the straw and the bottle.
