The 1943 St. Louis Glider Accident
The History Guy remembers the 1943 St. Louis Glider Accident. It is a nearly forgotten tragedy that underscores the difficulty in managing military contracts in time of war. The History Guy uses media that are in the public domain. As photographs of actual events are sometimes not availab

Make Sodium Magnesium Oxide Aggregate - A Substitute for Sodium Metal
In this video we make sodium magnesium oxide aggregate. A useful substitute for sodium metal in most cases. Doing this is very simple, we combine 30g of magnesium metal turnings or powder and 40g of sodium hydroxide in a metal container. The mixture is ignited with sparklers or a fuse and

FAIL: Gallium and Aluminum Thermite
In this video we fail at making thermite from the gallium infused aluminum. The objective was to see if the weak gallium infused aluminum could be used to make aluminum powder without going through the arduous filing step necessary for bulk aluminum. Turns out the gallium infused aluminu

Lab Equipment: Aspirator Vacuum Pump
In this video we demonstrate the Aspirator Vacuum Pump. A very important piece of lab equipment for generating a vacuum. It's very cheap and ingeniously simple by using the venturi effect to harness the power of a high speed water jet to create the vacuum. Because of such operation, it's v

Make Ethyl Propionate by Fischer Esterfication and Molecular Sieves with a Soxhlet extractor
In this video we synthesize Ethyl Propionate by Fischer Esterification but help along the process using molecular sieves and a soxhlet extractor. Esters are formed by reacting acids and alcohols. A byproduct of this reaction is water. Unfortunately the water present can react back with th
