1573

Gpdone, both you and Gahd have very interesting ideas; I'd love to hear more about each of them and any that others may have. After talking with one of my teachers I have come up with a research topic for my project. I'll be testing how polarizing the water will affect sonoluminescence. I'm thinking of getting two strong electromagnets and positioning them on opposite sides of the apparatus to where similar poles are facing each other. Perhaps by using the diamagnetic properties of water to force the hydrogen end of the water molecule to point towards the center will increase the energy output.

That's an interesting idea Ghad. I just read somewhere that adding an amount glycerin to the water increases the intensity of the light from the bubble by quite a bit. Any ideas on this? For now I'm just hoping those ultra high speed cameras (you know the ones that take 500 million frames per second) go on sale at walmart, so we can see just exactly what's going on here.

Who here knows and uses x86 assembly language, and if not asm what do you program in?

Here is a government site that has some information on sonoluminescence, and an experiment they did: http://www-phys.llnl.gov/N_Div/sonolum/ Here is a site with general information, and how to set it up: http://www.physik3.gwdg.de/~rgeisle/nld/sbsl-howto.html I got a good deal of my research at a local university, mostly science journals, and science magazine articles. Typing in sonoluminescence in google returns a lot of information; the sites above are just the ones I found to be most helpful on getting a general idea on the phenomenon. The thing about sonoluminescence is that no one really knows what causes it to happen. Theories on the source of light in sonoluminescence range from the idea that a small jet of water travels through the cavitating bubble at many times the speed of sound, and "fractures" the water in the same manner as a wintergreen mint releases light when it fractures, to the idea that the source of light is caused by fusion. It’s definitely an interesting phenomenon. P.S. 1573 actually does not relate to my birthdate. Nice guesswork though

Thanks, I came across that site in earlier research, and it provides a good deal of information to get started. I can probably aquire most of that equipment fairly easily. What I want to do though is work towards an original idea, or at least strong research that build on a previously though up idea. Would developing a way to view the phenomenon directly and visually contribute much to the research efforts? I'm not too sure how I could do that, since the cavitating bubble that produces the light is on the scale of a few micrometers at its widest. Maybe investigation into the possiblilities of fusion that have not been conducted yet? Most of this would be a bit ambitious for me, considering I only have a timeline of 2 -3 months to put all of this together into a nice neat little package for competition. Thanks

I want to work with sonoluminescence, but i don't know what I should investigate in this phenomenon. Many people have developed theories for what causes sonoluminescence. should I build upon a theory, develope my own, devise a way to take actual direct measurements of the phenomenon (from what I've seen most has been indirect), etc.. Thanks.

I am a high school student who is working on a science fair project dealing with sonoluminescence, but I dont know what to do with it. Anyone have ideas or suggestions? Thanks.

If one were to specially outfit an electron microscope to shoot a beam of electrons through a sample of water, how would the water deal with the beam? Would the water absorb and distort the electron beam? Thanks.
