Does The Squidy Sink?

Squidy was a little “squid” in a 2 liter bottle that floated at the top, and when you squeezed the bottle, Squidy sank to the bottom. Then, when you released the bottle, Squidy would float back up to the top. Squidy used some of the gas laws and principles we learned in class such as: Boyle’s law, Pascal’s law, and Archimedes principle.
Pascal's law plays a major role in Squidy. Pascal's law is about applying pressure, and when we applied pressure to the bottle, it forced Squidy to sink. The reason it sinks is because when you squeeze the bottle, it forces some extra water into the “Squid” itself causing it to weigh more making it sink.
Boyle’s law says when you increase the pressure the volume will decrease and vice versa. When there is pressure added to the bottle, the volume of the water decreases and some water goes up into the “Squid” because matter cannot be created or destroyed, but this causes the water displacement to be uneven. This results in the Squidy sinking. When the pressure is released, the volume can increase which enables the water in the “Squid” to exit it and even out the water displacement allowing the Squidy to return back to its original state. …show more content…
Archimedes Principle states the body immersed in a fluid has to be equal to the weight of the fluid that the body displaces. When pressure is added, it causes the fluid being displaced to be uneven which results in the sinking of the Squid. When the pressure is released, the fluid evens out which allows the “Squid” to float back up to the top. The reason the Squidy works is because of Boyle’s Law, Pascal’s Law, and Archimedes Principle, and their relationship with to each other. The experiment would not have worked without all three laws/ principles. Squidy was a fun interactive experiment to do to help us learn about gas laws and
