the question is: have you owned one for yourself

Bernoulli's Principle

A change in pressure at any point in an enclosed fluid at rest is transmitted undiminished to all points in the fluid

3 or 4 balls at a time

For the truly daring (and make sure you're sitting down for this little dose of reality)

STEM Box: Ferrofluid (Invented by NASA) (Ages 8 & Up, with Adult Supervision) engineering the question is: have youFerrofluid is a liquid (such as water) holding tiny particles of iron compounds that become strongly magnetized in the presence of a magnetic field. You may ask: why don't the tiny particles ever settle out of the liquid to the bottom? The answer is that the particles are submicron size (i. e., nanoscale) so that the surface area of each particle is extremely large in relation to its mass. Because of the small particle size and large surface area, the
