Description
ok,no one else will like tihs, but I, yes I wanted to put this in because i am a science geek and i really like this because it is a pic i took whilst we were doing a physics experiement. The light spots on the bubbles are due to what we call light interference where the wavelengths of different coloured lights interefere constructively and its really really hard to explain! but any good physicist will understand.Might take this off later, but wait to see another comment from me later explaining fully whats happening here...am running short on time now! must run off and graduate...bubbye!

yea, please explain whats going on...
i'm almost scared to find out.
kinda freaky eh?

ok, what happens is light shines into the surface of the bubble, and some is completely relfected because its at such an angle that none can penetrate, and we call this total internal relfection...this is what's happening here. ( and you can only probably appreciate its true beaty and symmetry is you're a physicist)..but sometimes the reason we see light on bubbles is because white light, which is the light that is all around us, breaks into colours when it hits the bubble because the wavlength of the light in white light whih reacts striongest to the density of the bubble mixture relfects and makes constructive interference, and this is thew colour seen...i hope this makes sense! hehehe

yes, and frogs too i forgot to mention. needless to say, i didnt take anymore biology classes.

hey that's cool, but they coolest thing i've even done is.. with sulfuric acids, we placed a sulfuric acid 2.0 or sometin then we placed a magnesium carbon thingo and then it disolves and makes gas and we trapped the gas in another test tube, and u light a match and place near to the mouth of the tube with the trapped gas and you'll see a ball of smoke moving around in the tube... man that was awesome! I am not a science geek though... i just had to do it for freakin sceience experiment

omg 
all that chemical stuff sounds really interesting...thank for sharing

hahaha so true...and putting our dressing gowns over our clothes so mum wouldnt see we'd not slept at all...watching the sun come up and trying to hide the "next" that the study got turned into with discarded papers and coffee mugs, chip snacks and the like from mum...heh heh heh...good times...aaahh..

i took it with one of the school's digitals...and i kid you not when i say it was bigger and heavier than the brick...the only light in the room was from the falsh, so it was hit or miss because it was pitch black!

ah yes, but the chemist is interested more in the forces that are at work here, namely surface tension which causes the bubble to exists in a spherical manner. And the manner in which the amphoteric molecules in the surfactant solution hold together by hydrogen bonding and the like
