I actually used twine that you can buy in the grocery store, but yarn should work as well. The key will be to wet your yarn 1st, and make sure your yarn is as taut as possible when you begin pouring the water down it. Also, begin by pouring slowly.
Thanks for the question. Although the focus of this video is cohesion, both cohesion and adhesion are demonstrated in it. Cohesion is demonstrated by water connecting to water along the surface of the string and traveling down it in a “stream,” as explained in the video. What I neglected to point out in the video is that adhesion is demonstrated when the string is dipped in water (1:37 minute mark) prior to the attempt at getting water to travel down the string. Definitions for both cohesion and adhesion are given at the 0:45 minute mark.
Now thats an amazing experiment! Trying that this weekend!
Glad you like it...great to hear from you!
This was wonderful to see! Thank you so much for creating this video. I'm definitely sharing it with my students.
I'm truly glad you found it helpful!
Excellent. I am sharing this experiment with others. Keep them coming, Dr. Boyd!
No this is Adhesion not cohesion
So kool
are you using yarn? because yarn is the only thing i have to try this. so can i use yarn and it still work?
