Soundwave Technology to put out fires?

Here is another form of technology that I found today that caught my attention.  Students in George Mason University found a way to use sound waves to put out fires.  In a way, it is a form of wearable technology.  One of the students said that engineering was way of finding solutions to complicated problems.  Instructional Designers should have this mindset as well!  Check out the link for more info on this technology!  It's pretty cool
