Dive into physics with this memorable and dramatic demonstration of Pascals Law. Simply fill the tool with a liquid, such as water, push in the piston plug, and watch the water squirt out of the holes in equal form and direction.

Not only wonderful for illustrating exactly how pressure is transmitted through water evenly, pass this nifty device to your students and give them a fun hands-on learning experience.

Portable and lightweight, this demonstrator is easy to handle and simple to use.


What You Get

Pascals Principle Demonstrator. Features a 25cm borosilicate glass bulb, equipped with a section of 5cm diameter holes, and a piston for easy compression.

How Does it Work?

Pascals Principle Demonstrator functions exactly like a modern hydraulic lift, but features a method which is easy to visualize. As pressure is applied to the piston with a push of a finger, the fluid enclosed within the borosilicate glass bulb is forced out the holes equally every time.
