Pascals Law Experiment
Corey Sparrow, Jose Mijares, Tanner Lindle
- A water bottle
- A rubber balloon
- A rubber band
- If using matches, cut off the heads of The match and put them in the bottle. Discard the wooden end.
- Fill up water bottle completely
- Cover the top of the water bottle (where the cap would go) with the balloon
- Secure the ballon by tying the rubber band around the bottle
- Press finger repeatedly on the opening that the balloon is covering
- Repeat and record results
Observations during experiment
Proof of theory/results
The match heads moved down due to the pressure that is transmitted through the water. When the finger is pressed down on the part of the balloon connecting to the mouth of the bottle, a small quantity of water penetrates into each match head, which adds enough weight it causing it sink. When the finger is removed, there is air pressure inside the tooth picksheads to force out the water and make the match heads rise again. Because pascals law states that "pressure exerted anywhere in a confined incompressible fluid is transmitted equally in all directions throughout the fluid" Pascal’s Law is proven by the results.
