| In this episode of Scientific Tuesdays, We will show you a very cool experiment using magnets, needles and some tape! Take some string and measure out the perfect distance to the magnet and then tape it off to a wall. You want to get the needle to float in mid-air using only the magnetic field as the force holding it up.
