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.

TPB #72 – More Liquid Droplets and Valve Sensor Cleaning

Posted by:

In this video I talk about how to get tall droplet spouts by adding a gum and a dry aid to the water, and adjusting the drop size. This video also goes over how to clean the valve if you forget to flush it out after a photo shoot.
