Tautochrone Track [1st Ed.]

30.00 50.00

This one off model demonstrates the curious properties of a brachistochrone curve, by which the metal balls will all reach the bottom of the track when released simultaneously, regardless of their position on the curve. The 5 metal balls are suspended from underneath with hidden magnets. Press down the tabs on either side of the model to release the balls. See my video all about it!
