Bernoulli's eyes would pop out if he saw these!

Eyepops are a fun, simple way to explore how air pressure changes with velocity. Blow into the mouthpiece, and the eyes float on a stream of air! Daniel Bernoulli explained in the 18th century that the pressure decreases as the speed of a moving fluid increases.

The higher atmospheric pressure surrounding the stream of air keeps the eyes floating in the stream. Explanation and other Bernoulli experiments included.
