I believe you will find your answer here: http://www.uah.edu/research/resrev96/Micro/students.html I paste a short submission of this page that should answer your question: Using $1.29 acrylic boxes from a dime store and simple electronics, undergraduate students and their UAH lab instructor are doing cutting edge research into sonoluminesence, a little understood phenomenon sometimes referred to as "a star in a jar." In a back corner of a teaching lab, the student-built apparatus uses acoustic waves to suspend a microscopic bubble in water. Stretched and compressed by the force of sound waves, the bubble expands to a diameter of only 100 microns, then collapses to one one-millionth of that volume. It does that 30,000 times a second, focusing acoustic energy by a factor of one trillion, generating temperatures hotter than the surface of the Sun and releasing with each cycle a faint flash of light that lasts 30 trillionths of a second.
