The self-starting siphon uses scientific principles to initiate and maintain the flow of liquid through the siphon tube. This version is great for magic shows or to show off to friends. To perform the demonstration, simply fill up a cup with liquid and drop in the siphon. The cup must be nearly completely full in order for the siphoning effect to occur!

For more explanation behind the science of the self-starting siphon, watch "This Tube Makes Water Flow By Itself" on YouTube by The Action Lab (link below). https://www.youtube.com/watch?v=nA_ZTkLYNtA&t=236s
