Self-starting siphon experiment

I stuck on the end of the straw and the liquid will flow upward down the tube under the pull of gravity. Depending what the liquid is it could taste really bad.


When you release your finger the water will rise up and go over the edge and continue to go until the water level is at the same level as the end of the straw inside the glass.


By moving the tube up and down and tapping the other end with your finger it creates pressure difference that causes the liquid to flow from high pressure to low pressure, and thus into the submerged end of the tube, this will bring the water up the tube, over the peak and down the tube, out the open end.
