I charged the balloon by rubbing it with a piece of fur. You can use a person's head of hair if you wish as well. I do not have hair so I usually resort to the fur.
@captaindisguise It is my understanding that as the soap spreads out on the surface of the water it pushes the pepper to the sides. Then the surface tension of the water is weaker so the pepper then breaks through and sinks.
So does Surface Tension Increase when the radius is larger and decrease when it's smaller, or is it the other way around. I can not seem to grasp this concept fully.
I do sincerely hope & wish you eventually re-shoot with increased narration volume. I think you & I are in the same fraternity . . . science teachers. Your vid has excellent substance; however, due to the low volume, (and the limited volume of classroom projectors) its greatness is lost upon my students.
Great substance; however even the best substance is lost or goes undelivered in the absence of supporting style. This Vid needs a re-shoot with narrator volume turned UP.
Hey by the way I suggest getting a set of computer speakers and using them in class. I got a set that actually has a subwoofer and it brings all mutlimedia to life in the classroom!
Nice video. However, the capillary action in celery bit is a misconception. Capillary action is responsible for only a few centimeters worth of water rising up through plant tissues. Cohesion and surface tension play an important role in the phenomenon, but not capillary action. Look up "cohesion-tension theory" to learn about how plants move water up their stems.
Thank you! Feel free to use this to teach your students. That is th exact reason why I created it. Most clips were taken over the course of 2 years in my science class and then I put it all together into one presentation. :)
emmaly77, I'm glad you liked the lesson. I'm interested in what class this was used in. I like the idea of reaching up to the university level! Thanks.
Thanks for all the information. It really helped.

Hey, i have a question, at 6:52
Why did all the pepper move away to the sides of the container ?
Thank You

Great Vid, but even with my 400 Watt Sub-Woofed, tricked-out classroom speaker system, this incredibly informative video is just too whisper quiet.

This is an excellent educational video. I will use it to teach my students about cohesion and adhesion. I'm sure they will enjoy it very much!
