Drake Glau Posted November 8, 2010 Report Share Posted November 8, 2010 Do you have any more specifics?God I hope so...Ummm...nope I got nothing but a buoyancy thing maybe but I don't know how that'd work out =/ Reply Link to post Share on other sites More sharing options...
JavierG Posted December 21, 2010 Report Share Posted December 21, 2010 I got one on my head, it has to do with electrostatic If you blow the ballon to a pretty big size and then rub it with wool or something of the sort (you hair could also work) you will charge it up. Then, inmediatly you have to pour water on the ballon, and you will see how it won't touch it.It has to do with the fact that the ballon is charged with electrostatic electricity, and the water molecules are polar, so the are repelled.If you like my idea, I can give you a few more tips. It's actually an intresting lab to do, and it has a bunch of things to comment. Reply Link to post Share on other sites More sharing options...
larry Posted December 22, 2010 Report Share Posted December 22, 2010 buoyancy... well, you could do volume of air in balloon against the force the water exerts upwards on the balloon.Could you do something with air pressure - diameter of balloon in air vs. submerged in water (measurements could be hard...)Is water in the balloon an option? If you could get hold of different balloons you could test the strength of the rubber against its thickness (waterbombs would be one cool way of testing this - for each thickness see what height you'd have to drop the water-filled balloon from to make it explode . Ok, maybe getting a little carried away here...) Reply Link to post Share on other sites More sharing options...

Is it possible for more information about this? It would be greatly appreciated. Reply Link to post Share on other sites More sharing options...
