In this video, I use egg whites to display the tubeless siphon. It’s a fantastic phenomenon where a fluid is attracted to flow upwards without a tube, which is related to the properties of the fluids themselves. In this experiment, the egg white can still be drawn into the syringe after the tip of the syringe leaves the liquid surface, which is an example of the tubeless siphon. As a comparison, water cannot enter the syringe after the tip of the syringe leaves the water surface. This contrast illustrates the unique properties of egg white: it has a higher extensional viscosity than water.
