Code Number: 2B20.40
Demo Title: Pascal Vases
Condition: Excellent
Principle: Pascal's Law
Area of Study: Fluids
Equipment: Pascal vases, Colored water.
Procedure:
Add water to the vases as necessary before doing the demo. Using the water bottle with the green colored water, add water into the large diameter tube only. Adding water into any other tube will create air bubbles which will make the demo unusable until the bubbles are removed.
