About This Product
Pressing the same block into sand on its wide face and then on its narrow pins, with a 500g weight on it, shows the footprint deepening as the area shrinks, which is why snowshoes spread weight and nails pierce. Further activities measure liquid pressure rising with depth, show the force of the atmosphere with the hemispheres, and use the overflow can and balance to find the upthrust on a submerged body and explain floating and sinking. Schools, colleges and institutes in Gambia, Solomon Islands, Brazil, Oman, Angola and Benin can order the Pressure, fluids and flotation from Educational Instrument.
Frequently Asked Questions
How does the kit show that pressure depends on area?
The same block and 500g weight are pressed into sand first on the wide face and then on the narrow pins. The pins sink much deeper because the same force acts on a smaller area.
What is the overflow can used for?
A body lowered into the full can pushes out its own volume of water, which is collected and weighed to compare with the upthrust measured on the balance.
