  • Thanks for all the information. It really helped.

  • Gay title

  • why is this homework for me?

  • really great stuff! this helped me a lot with my assignment, thankyou heaps :)

  • What are the songs used on this video? Very good explanation and examples, keep it up.

  • Like if your a student of doctor romano.

  • 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.

  • Charge the balloon by rubbing it with what?

  • Hey, i have a question, at 6:52

    Why did all the pepper move away to the sides of the container ?

    Thank You

  • @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.

  • i love watching cohesion

  • the balloon thing is so cooll!!!

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

  • Wow im using regular mac speakers and its pretty loud.

  • 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.

  • Wow, I hate science because I dont understand it but this video is awesome! THANKS

  • so thats how soap gets things clean :)

  • Mr. Temme,

    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.

  • Thanks.  I know about the volume but have not found the time to fix it. :(

  • 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!

  • yes thank the lord, sombody actually taking the polarity of water seriously, I'm learning this in school right now so its a huge help.

  • Same here..!!= ).

  • same here..!!XD

  • me no likey big words...

  • i like pie!

  • Wow this is way cool!

  • pshh...ok, w/e

  • PERFECT!!!

  • i just learned something today

  • Nice job. I love the video and I think my students will too. Excellent production!

  • 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.

  • 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!

  • 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. :)

  • im studying education at uni and taking science this semester and we looked at this vid in class. Very interesting and helped me learn alot. Thanks

  • 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.

  • great vid, i actually learnt something!!!!

  • Thank You!!

  • hey exellent video man! Great work
