A Sub I Can Actually Afford

A great website called howtoons produces cartoon how-to guides to build a variety of thing to teach children, and adults, basics of engineering and science. My favorite is the Soda Bottle Submarine. When I am back ashore I plan on building a whole fleet and taking over the world.

Craig McClain is the Executive Director of the Lousiana University Marine Consortium. He has conducted deep-sea research for 20 years and published over 50 papers in the area. He has participated in and led dozens of oceanographic expeditions taken him to the Antarctic and the most remote regions of the Pacific and Atlantic. Craig’s research focuses on how energy drives the biology of marine invertebrates from individuals to ecosystems, specifically, seeking to uncover how organisms are adapted to different levels of carbon availability, i.e. food, and how this determines the kinds and number of species in different parts of the oceans. Additionally, Craig is obsessed with the size of things. Sometimes this translated into actually scientific research. Craig’s research has been featured on National Public Radio, Discovery Channel, Fox News, National Geographic and ABC News. In addition to his scientific research, Craig also advocates the need for scientists to connect with the public and is the founder and chief editor of the acclaimed Deep-Sea News (http://deepseanews.com/), a popular ocean-themed blog that has won numerous awards. His writing has been featured in Cosmos, Science Illustrated, American Scientist, Wired, Mental Floss, and the Open Lab: The Best Science Writing on the Web.

  1. That is very cool. The propeller “design” is fascinating, but I don’t think super efficient. But the whole idea… you could teach a pretty good physics course just using this thing. Neutral Buoyancy, why you need the ruler – angular momentum, tilting the ruler to get lift (up or down), amount of energy in the rubber band to move the thing… You could even do quality control statistics by building 6 or 7 and comparing…
