RetroProto podcasts bring all the novelty of our video shows to listeners on the go! Welcome to our first podcast. Today we're handling a shallow terranean crawlspace by creating more space under the building. The plumbers who are coming to crawl down under there will be much more comfortable, so they'll be able to focus on fixing the pipes. We're using an invention composed of a shop-vac, a reinforced cardboard box, a jumbo funnel and lots of tubing.
