Add the funnel to your bottle and carefully pour your water into the bottle.

Water bottle fountain experiment.

Once the water drops below the level of the outlet tube in the fountain supply the heron fountain will stop. If the bottle is wet the blu tac will be hard to stick. This experiment has lots of variations and many different ways of building depending upon time and resources. We might just decide to feature it here.

Science behind this science project. 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. Wear a thick glove or oven mitt to handle the bottle. You will find a beautiful colored water fountain starts to shoot up in your water bottle without any mechanical pump and electricity.

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. If you make one why not film it and upload it to youtube you never know. 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. This is due to equal air pressure pushing downwards through the opening of the straw and the bottle.
