TPB #82 – Airgap Flash Reflector Update

Posted by:

The airgap flash works well up close, but it would be nice if the light was more focused so it could be placed further from the target. Here I use laser cut acrylic pieces to build a reflector for the airgap flash and then test its performance.

TPB #74 – Air Cannon

Posted by:

In this video I describe how to take photos of flying ball bearings shot from an air cannon. I also go over the different energies in this versus an air pellet, and how that kinetic energy gets distributed into the target.

UPDATE: Alan pointed out my energy calculations were off by a few orders of magnitude and wikipedia confirmed it (http://en.wikipedia.org/wiki/Joule). The units for Joules are kg*(m^2)*(s^2). My units were g*(m^2)*(s^2). So to ...

TPB #73 – What Water Droplets Do Under the Surface

Posted by:

In this video I show what water droplets do under the surface when they splash into the liquid reservoir by using a clear glass reservoir. I show what happens with one drop and then two drops. This explains a lot about what’s happening and why two drops are required for those really tall water spouts.
