A vertical cylinder with holes at different heights demonstrates that water pressure increases with depth. Students observe that the horizontal range of water jets increases for lower holes, providing visual …

Bernoulli's principle and the Coanda effect stabilize a beach ball in a leaf blower's airstream. Students predict which ball — light or weighted — remains stable at larger tilt angles, …

A jet of compressed air blown across a bench lifts a drooping sheet of paper, demonstrating Bernoulli's principle. Students observe the counterintuitive result that fast-moving air above the paper creates …

Blowing air through a spool holds a card against it rather than blowing it away, demonstrating that high-velocity flow creates low-pressure regions (Bernoulli's principle). Works even with the spool inverted.

Demonstrates terminal velocity and how it scales with mass for objects of identical shape. A stack of four coffee filters reaches twice the terminal velocity of a single filter, so …

Demonstrates vortex ring formation and propagation. A fog-filled cardboard box launches visible smoke rings when struck, showing how a sharp impulse through a circular opening produces a toroidal vortex that …

A toy smoke-ring launcher generates visible vortex rings, demonstrating vortex formation, stable propagation of rotational flow structures, and the role of circulation in fluid dynamics.

Demonstrates shear-thickening (dilatant) behavior in a non-Newtonian fluid. A cornstarch-water mixture on a vibrating speaker forms dramatic "dancing" tentacle structures, showing that viscosity can depend on applied stress rather than …

Demonstrates rate-dependent mechanical response: Silly Putty flows when pressed slowly but shatters when struck with a hammer. Students see that a material's behavior as "solid" or "liquid" depends on the …
