the whole row of 16 blocks could be all one colour)

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

and you instantly feel the cold of the ice cube

This is so counter-intuitive and so cool - both ways

STEM Box: Ferrofluid (Invented by NASA) (Ages 8 & Up, with Adult Supervision) engineering the whole row of 16Ferrofluid 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
