More slinkies dropped independently

 

Since releasing the slinky carefully has proved to be a problem because of friction between the hand and slinky, a black false leather glove was used to lower the effects of friction on releases. In half of these new clips taken, the slinky was released using a glove. Using this method greatly increased the chances that the slinky would contract uniformly without tilting to the side upon release.
