Water Bottle Fountain Experiment Explanation

A siphon is a way to carry water uphill without the use of pumps.

Water bottle fountain experiment explanation.

Create a miniature fountain in a bottle with a straw adhesive putty and the nifty physics of thermal expansion. This really cool self pouring liquid science trick is a great experiment to try at home. You may want to. Make a non stop water fountain out of 3 plastic bottles and straws.

This experiment allows children to see that air takes up room and is always present even though we can t see it. 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. Pour the vegetable oil in the bottle until is almost full. The higher pressure outside the bottle forces the water up.

Once the water drops below the level of the outlet tube in the fountain supply the heron fountain will stop. 2 12 see the bottom on how to simplify or extend to meet the needs of your child materials. 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. A combination of gravity and atmospheric pressure drives the water through the hose even if parts of the hose.

These kinds of science projects help kids a lot to learn various science principles in easy and creative manner with lot of fun. 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. Fill the bottle up about 1 4th 1 quarter with water. That pushes down on the water in the bottle pushing it through the straw and making the fountain stronger.

When you place the inflated balloon on top of the bottle the air pressure on top of the bottle becomes higher. The same happens with the water in the straw.
