Physicists around the world tackling the fuel crisis... and making superlenses out of tin cans. Not everything can be all work no play.

Sooo this is my first blog, I would do a 'this is my first blog, that is all' but to be honest it seems a tad mundane. Instead i'll jump straight into it with an odd bit of physics I stumbled upon. Admittedly at first glance you wouldn't expect this to be that significant, but in the broad spectrum of things it opens up masses of ways to manipulate sound that have never been seen before. Arranged in a grid as such the tin cans can focus acoustic waves into areas much smaller than their metre long wavelengths usually allow (a few centimetres in this case). Right now it just looks like a couple of lazy uni students have left some tin cans on the floor... in a specific grid... surrounded by very expensive equipment *cough* but this technology could eventually be used in biomedical fields for cell sorting or for particle removal in ultrasound cleaning. I suppose the only question left is would the same experiment be better or worse with pepsi cans...
