The Absorbency of Rock
Did you know that rock can actually absorb liquid like a sponge?
This experiment shows you how to prove it.
The Brazil Nut Effect - Experiment
In Stratification And Segregation: Why Does Some Sandstone Have
Stripes? Hernán Makse shows how sand grains of different
sizes and shapes may naturally separate after being thoroughly
mixed together.
Building the Hele-Shaw Cell
Find out how you can build a "quasi-two dimensional vertical
Hele-Shaw cell" to see how sand grains of different sizes
and shapes may naturally separate after being thoroughly mixed
together.
Experiments with Quartz
Triboluminescence is light that is produced by pressure, friction,
or mechanical shock. An alternate method to show the piezoelectric
effect is to heat a fair sized quartz crystal in an iron skillet.
Porosity
How much open space is there in rock? In this experiment we check
the porosity of gravel, sand and silt, the raw materials that
sandstone is made of.
