How to Make Water Music – Slap, Plunge, Plow!

Female musicians from the northern islands of Vanuatu use the water surface as an instrument to create a variety of unique sounds – slap, plunge, plow – which they accompany with singing. Each interaction with the water surface produces a different acoustic response corresponding to the air-water-hand interaction, each of which has been studied by Randy Hurd and Tadd Truscott of Utah State University.

Vortex Ring Collisions and Transition to Turbulence

Vortex ring collisions are incredibly beautiful and also incredibly complex. Ryan McKeown of Harvard University explains his amazing experiments visualising colliding vortex rings and their transition to turbulence.

How does Stone Skipping work?

By bouncing elastic spheres across the surface of Bear Lake in Utah researchers have discovered the physics behind stone skipping. The mechanism of ‘water walking’ occurs when a deformed sphere rotates continuously across the surface of the water giving the appearance that the sphere is literally walking on water.

Air Pollution Risk of Cooking Oil Droplets

Cooking oil in a frying pan can be dangerous when the ‘explosive’ droplets touch your skin, but new research shows that they also increase the risk of indoor air pollution if not properly ventilated. Interview with Jeremy Marston and Tadd Truscott at Texas Tech University and Utah State University.
