A while back I was asked by MAKE Magazine to come out to their headquarters and teach a quick lesson as part of their Maker Camp, a virtual summer camp conducted via Google Hangouts. Each day they host a number of hangouts to discuss different projects their virtual campers are working on as well as a demonstration of various tools or techniques for making all sorts of interesting things.
My demonstration: making a couple of simple molds for prop building. You can watch the whole thing right here:
I did a detailed write-up about the one-sided mold a few days ago, but I'll also be doing an in-depth article about the two-sided mold just as soon as I get a chance to get a few more photos of the molds in progress.
