How Fast Does a Fidget Spinner Spin
Description
How can you measure the precise rotation speed of a fidget spinner using simple household tools? This video demonstrates a method for calculating RPM (revolutions per minute) using standard video footage. The process takes into account the camera's frame rate and the optical phenomena that occur when the rotation speed exceeds the sampling rate.

Why Is the Ocean Salty?
Credit: מכון דוידסון לחינוך מדעיThe salinity of the oceans stems primarily from the erosion of rocks on land by slightly acidic rain, which dissolves minerals and carries them through rivers into the sea. As water evaporates from the ocean surface, these salts are left behind, their concentration steadily increasing over billions of years. Additional sources of salt include hydrothermal vents on the seafloor and underwater volcanic activity.2:33
