The iPhone4S has captured a lot of hearts (and pictures) with its impressive built-in 8 megapixel camera and there are many owners who feel the phone has made the compact digital camera obsolete.

Now it seems the iPhone has turned its lens to science: a blogger on Scientific American recently found that adding a drop of water on the camera’s lens turns the device into a microscope.

The iPhone4S is the camera of choice here at our Tokyo office, so we couldn’t help trying it ourselves after hearing the buzz.

Taking care not to get water on any other part of the phone, we took a single drop of water, placed it on the lens and…it actually works!

The process is simple and, after repeating it several times, we found that the image blurs with any more or less than a single drop of water.

Equipped with our new makeshift microscope (just add water!), we took out a 1000 yen bill, pointed the camera at the right eye of the good Mr. Hideyo Noguchi and *snap,* we had an image capturing a level of detail normally invisible to the naked eye!

Overwhelmed with a craving for science, we macro-snapped everything around us: our fingerprints, hair, the carpet (which was much dirtier than we thought!)…

We’ve uploaded the result of our attempts below, all of which were taken with nothing more than the iPhone4S and a drop of water. If you want to try it yourself, we can vouch that no damage is done to the lens—just be careful to wipe up when you’re done.
