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.

Excellent video quality and production! I feel that this video is perfect for many audiences wishing to attempt this same experiment in the future.
The quality of this video is incredible and shows a cool experiment, great work! The phenomenon is not something I have seen before, so I appreciate the educational value!
Haotian, this video was fantastic! The color contrast used for the egg white portion was clear and sharp. I liked how you showed the fluid phenomena differences between the water and the egg white. Excellent photo quality with the experiment in clear focus and the background blurred to focus the eyes on the fluid flow specifically; nicely done!
Hi Haotian
I didn’t know of this phenomenon before viewing this video. This is really a unique property of such liquids and you did a great job of capturing it. I agree with Peter, the video production quality is very good and looks professional.
Great work!
Your video is incredible. I like the color contrast between the background and the egg because it helped make the visual clearer.
Absolutely amazing videography! I feel that the experiment was clearly in shot the entire video, and the subtitles were concise and effective.
I think the video production is very good quality. Good job on your presentation.
