About This Product
As the pressure difference is increased, students watch the membrane bulge and finally give way, which shows that pressure acting over an area produces a force. The demonstration supports lessons on atmospheric pressure, gas pressure and the link between pressure, force and area. Face and hands are kept away from the membrane while pressure is applied, and the pressure is released slowly afterwards. Educational Instrument can arrange export supply of the Pressure tear device to Sudan, Poland, Bosnia and Herzegovina, Madagascar, Kazakhstan and Chad.
