On this episode of How To Make Everything, our host says, “This year, I’m making money! Specifically, I’m going through the history of money and recreating the various forms of currency as they evolved through history. In this video, I explore both the origin of money and learn how to extract my own precious metal from the earth.”

On this episode of How To Make Everything our host collects some copper ore from an abandoned mine in California and extracts the copper metal out of it through electrowinning.

This magical moment was captured on January 10, 2017 in Queensland, Australia: “I am a female boulder opal miner in outback Queensland. In this video, I share one of the most amazing moments that I get to experience with my team; exposing an opal and being the first person on the planet to gaze upon its natural beauty. To find, extract and split a raw boulder opal is simply like no other experience. At our ethically sustainable mining site, we split boulder opal along the opal vein running though ironstone rock every day, if we’re lucky. This boulder opal that we split open has gem grade black opal inside.”

On this 2nd episode of Planet Slo Mo, we take a thermal look at a geyser and learn what makes them blow. Gav & Dan are Brits, so they pronounce it “geezer.”

On this first episode of PLANET SLOW MO, Gav and Dan travel to the volcanic island of Iceland to capture thousands of liters of boiling water exploding in slow motion. They also thought it was a good idea to put the Phantom on a drone. Was it a good idea? Let’s find out.
