Another balloon being shot

Posted by wildwatertv on March 24, 2010

I bought a new Chinese air rifle yesterday for using in just this way, it’s pretty powerful and the pellet is travelling at 500 feet per second as it bursts the smoke filled balloon showing clearly the sound wave that is generated by the ‘pop’.  It’s so fast that the balloon still retains its shape as the pellet leaves the frame.  This is similar to another image on the blog, but with all new digital techniques.  Still looking to speed the flash up a little to freeze the leading edge of the rubber as it moves, but the speeds are unimaginably fast.

crystalline rocks

Posted by wildwatertv on March 10, 2010

This is a weird sort of image, made possible by the art of a stonecutter.  It’s a rose quartz section, about 2mm thick, photographed by shining light through it.  What is produced is a sort of graphic crystalline magic.  This technique also creates an interesting three dimensional effect, due to the varying translucency of the rock section.  Not through a microscope, but 1;1 magnification with a Nikon Micro lens.
