Water Bottle Fountain Experiment Explanation

A combination of gravity and atmospheric pressure drives the water through the hose even if parts of the hose.

Water bottle fountain experiment explanation.

The water in the basin contains gravitational potential energy and as it falls downwards it uses the pneumatic pressure of the air in the air supply container to push the water in the upper fountain supply container. Make a non stop water fountain out of 3 plastic bottles and straws. When you place the inflated balloon on top of the bottle the air pressure on top of the bottle becomes higher. It consists of a hose full of water with one end in a water source and the other end pouring out into a destination that is below the source.

The higher pressure outside the bottle forces the water up. These kinds of science projects help kids a lot to learn various science principles in easy and creative manner with lot of fun. 2 12 see the bottom on how to simplify or extend to meet the needs of your child materials. Pour the vegetable oil in the bottle until is almost full.

A clean plastic bottle try to use one with smooth sides water vegetable oil or you could use mineral or baby oil instead fizzing tablets such as alka seltzer food coloring watch scientist joe as he makes the lava lamp experiment here. That pushes down on the water in the bottle pushing it through the straw and making the fountain stronger. Empty water bottle balloon straw blu tac or similar tray for catching the water optional. This really cool self pouring liquid science trick is a great experiment to try at home.

You may want to. Fill the bottle up about 1 4th 1 quarter with water. The air inside a balloon is under pressure as it is squeezed by the rubber. Create a miniature fountain in a bottle with a straw adhesive putty and the nifty physics of thermal expansion.

Making a fountain in water bottle without electricity and pump is one of the very good and easy science projects for kids to understand the air pressure system and basics of fluid mechanism. This experiment allows children to see that air takes up room and is always present even though we can t see it.
