It was fun to use extension tubes for close - up photography. I borrowed them from my friend 
"Extension tubes work by increasing the extension of your lenses. An extension tube is a hollow, light-tight tube that fits between your lens and your camera mount. It moves your lens further from the camera, and the front element closer to the subject. The closer you can focus, the more magnification you get.
The biggest drawback of these extension tubes is aperture control. If your lenses don’t have manual aperture rings (ie the aperture setting is controlled by the camera) then the lens aperture will remain locked open at the widest aperture." Because of that, photos may look out of focus. <source>
