Weekend Activity Do a centrifugal force demo

Resource Info

Basic Information

Make your no cost oil centrifuge. All you need is a bowl & thread.

00 hours 40 mins

Tape three equal size threads to a bowl and hang it from a 50-cm long thread. Suspend the bowl with the thread and spin the bowl such that the thread is completely twisted. Now add some color water and some cooking oil to the bowl. On releasing the bowl it will start spinning fast and the water being heavier than oil it will be thrown outwards and will climb the wall of the bowl whereas the oil will remain in the center. This is a simple demo of a centrifuge.


Do a demo of centrifuge and check relative difference between the densities of oil and water.
