Making Sand Swim with Fluidization

Watch more with these video collections:

From the Ri Channel‘s View the Tales from the Prep Room series, this is how you make a fluidized bed of sand: Making Sand Swim with Ri Demo Technician Andy Marmery. Watch how these solids suddenly behave a lot like a fluid as air escapes between the sand particles, causing them to float.

Aided by a troop of floating objects Andy dusts off the fluidised bed, a classic piece of Ri demonstration kit handed down from the 1950s.

It’s definitely one of the more strange and fascinating demonstrations that we’ve seen.
