Water Bottle Fountain Experiment

You will find a beautiful colored water fountain starts to shoot up in your water bottle without any mechanical pump and electricity.

Water bottle fountain experiment.

This is the hardest part of the activity and is best done by an adult. This experiment has lots of variations and many different ways of building depending upon time and resources. 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 due to equal air pressure pushing downwards through the opening of the straw and the bottle.

We might just decide to feature it here. Empty the water into a jug so you can boil it again to repeat the experiment or pour it on a plant once it has cooled down. 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. Science behind this science project.

Fill a small bowl with cold tap water food colouring is optional but makes a much prettier fountain. If the bottle is wet the blu tac will be hard to stick. Once the water drops below the level of the outlet tube in the fountain supply the heron fountain will stop. Add the funnel to your bottle and carefully pour your water into the bottle.
