Also I noticed that the smaller ballon didnt totally deflate. Do you know at what point in the experiment the small bubble stops transferring air and why? Has it got something to do with radii or curvature of the surfaces?
Yeah, at some point the rubber in the balloon is no longer stretched... imagine an empty balloon that you have not inflated it is basically a bag-like piece of rubber that will not collapse. Think of a little pouch. The tension in a balloon is created by stretch of the rubber... the smaller the balloon gets, the more pressure it exerts - up until it cannot collapse any further because there is no stretch left in the rubber.
This is a great video but your videos would be ace if they had more science behind them, like explaining the science behind your demonstration. But still its a great video.
You might want to lower the volume of the music in the background. It's a little difficult to hear what you are saying with the music in the background. Thanks.
Haha, I think it adds something extra... plus our physiology is what makes pole dancing possible! :-) I did try to cover it up with a "thanks for watching" annotation though since I emailed it to my mam phys professor who posted it to the class website... did it not work? *blush*
I thought the balloons would behave exactly as they did when filled with air. But, if gravity is causing higher pressure in the larger balloon (due to the extra weight of water), I would expect the balloons to become the same size. When one balloon gets larger, it should empty into the smaller... Now I'm not sure about this, but maybe the water has momentum when it moves, and eventually this coupled with an increasingly small radius causes the large balloon to empty completely.
Wait if u have a bigger radius, wouldnt you have a bigger wall tension??? Because T = P x r. , so is wall tension the same as surface tension???

awesome video! thanks for the explanation and experiement.
when will you post the 'pole dacing' experiments and equations? lol
nice work!
;-)

Kudos on the experiment, but I don't understand why you felt the need to include a pole dance in a bikini at the end?

P.S. pole is really fun you should try it!
Yemmy95 2 years ago
my next suggestion would be to try it with He balloon and then you can extract some interesting results. carry on!

How about air or oil in the balloons, submerged in a swimming pool? I don't think I'd be able to set this up using He... could get expensive!
Yemmy95 2 years ago
So how about try to repeat the experiment with water, but this time underwater. ;-)
agerom 2 years ago
Also I suggest you repeat the experiment using liquids this time. Does this "object" to your initial "belief"?
agerom 2 years ago
I'll try it and post the result. I doubt it will matter though... can you give me a reason why you think it would be different?
Yemmy95 2 years ago
Ooooh... I need to think about this more. I posted the new experiment with shocking results! My initial thoughts:
1) Gravity has something to do with it;
2) If water goes from the larger balloon to the smaller, why do they not equillibrate?
Yemmy95 2 years ago
also what do you mean by "equilibrate"? What did you expect at first place?
