How to make glasses from Scratch

I recently collaborated with Andy George and his fascinating How to Make Everything youtube channel on a project. I helped Andy to make glass from scratch, using only the raw ingredients you can gather yourself from the natural environment. You can collect silica from sand, potash from wood ashes, and lime from chalk or limestone. Andy then ground his glass into lenses for a pair of spectacles. Have a watch of the video below here! There’s also a follow-on video with cartoon animations on why glass was so critical in the history of us developing science.

How To: Make a Gasifier Stove

For the launch of the book, we created a series of five short films to showcase different techniques that would be vital for surviving the immediate aftermath and rebuilding the capability of your post-apoclyptic society. This third one in a series of three shows how to make gasifier stove using nothing more than old tin cans. A gasifier stove burns fuel exceedingly efficiently and cleanly, and demonstrates the principle behind wood-powered cars that were common in the Second World War.  Also see (1/3) How to open a can without a can opener and (2/3) How to start a fire with everyday items, as well as How To: Electrolysis.

You can follow my step-by-step instructions to making your own gasifier stove very simply here.

How to start fire with everyday items

For the launch of the book, we created a series of five short films to showcase different techniques that would be vital for surviving the immediate aftermath and rebuilding the capability of your post-apoclyptic society. This is the second one in a series of three, which demonstrates how to make fire. Once all the matches and gas lighters have gone, here’s how to start a fire with everyday objects (which could be scavenged from the abandoned cities) used together in surprising combinations. Also see (1/3) How to open a can without a can opener and (3/3) How to make a gasifier stove, as well as How To: Electrolysis.

How to open can without can opener

For the launch of the book, we created a series of five short films to showcase different techniques that would be vital for surviving the immediate aftermath and rebuilding the capability of your post-apoclyptic society. This first one in a series of three shows how to open a tin can without a can opener, or any other tool. If you understand a little about how the tin can is constructed, you can exploit a neat trick to open the lid very easily. Also see (2/3): How to start a fire with everyday items and (3/3) How to make a gasifier stove, as well as How To: Electrolysis.

Electrolysis of water and brine

ElectrolysisFor the launch of the book, we created a series of five short films to showcase different techniques that would be vital for surviving the immediate aftermath and rebuilding the capability of your post-apoclyptic society. This one shows how to use a scavenged deep-cycle battery (perhaps from a golf buggy, mobility scooter or caravan) and the alternator from a car to keep your community electrified, and to perform electrolysis for creating crucial substances for yourself. Also see the linked series: (1/3) How to open a can without a can opener, (2/3) How to start a fire with everyday items and (3/3) How to make a gasifier stove.
