The Hand Boiler


 Model Description This is a demonstration of how pressure increases with temperature particularly at temperatures above the fluid’s boiling point.  Warming the bottom chamber beyond the boiling point increases the pressure sufficiently to displace fluid into the upper chamber.  This demonstration should take 5 minutes. Engineering Principle The pressure of a fluid increases as you […]

Fluid Properties


 Model Description This is a simple demonstration of the difference between density and viscosity in fluid mechanics.  Two equal size containers, one containing shampoo and the other corn syrup, are used to show the difference between the two concepts.  This demonstration should take 5-8 minutes. Engineering Principle Most students are familiar with density and viscosity […]
