Make Nitric Acid - The Complete Guide

We show 3 ways to make nitric acid based on two different chemical approaches both of which can be done using easily accessible materials. Warning: The procedures in this video produce large quantities of toxic gases and deal with highly corrosive acids. All work must be performed in a fume hood with proper safety equipment. And all apparatus must be glass to withstand the acids. Chemically, nitric acid is made by bubbling nitrogen dioxide into water. So the objective in this approach is to generate nitrogen dioxide. This can be done by reacting hydrochloric acid, a nitrate salt and copper. Around 80grams of sodium nitrate, over 30 grams of copper and 100mL of hydrochloric acid (37% 12M) are the quantities needed. The exact amount isn't critical. For usable concentrations, the amount of water being converted should be small, around 20-50mL. Any source of nitrate is usable including potassium nitrate, ammonium nitrate and even nitrate-based fertilizers. You can use our previous video on testing for nitrates if you want to determine if yours can be used. www.youtube.com The tricky part now is leading the gas into water. Two approaches are shown in the video. In the first approach three containers, such as jars are place inside each other to force the gas to go into the water. This is very inefficient but is very simple to do. The better approach is to lead the gas out of the generator through a tube and into a chilled container of water. The water that's converted into ...

Four Acres and Independence - A Self-Sufficient Farmstead

Peak Moment 168: Take a tour, accompanied by curious sheep and geese, of Mark Cooper's self-sufficient small farm. Over several years, he transformed a rundown house and hillsides of berry brambles into pasture and gardens where he produces and preserves most of his family's food. Visit the Goose Grotto in a constructed pond, a heritage fruit tree orchard, logs producing shiitake mushrooms, and a cheap-and-easy container kitchen garden. Mark gives us a closeup view of the solar dehydrator he constructed from salvaged materials - and his tips on food drying. He has husbanded up to fifty animals at a time, including two Tibetan yaks! This farmstead in Rough and Ready, CA lives up to the town's name ? and is a testament to hard work, wide-ranging construction skills, and love.

Rock River Arms AR15 Review by Nutnfancy

RRA produces some of the best high value AR-15 variants in the world. They are extraordinarily accurate, reliable, and long lasting. In this in-depth review vid, I address my thoughts on "mil-spec" and Rock River's departure from it. The QA portion of the spec is desirable but adds substantial cost and it generally overkill for the average AR user. It also limits features to those determined by US Government committees...a bad thing. The civilian market has long been where the best guns are made. Some forum elitists may balk at the materials of the Rock Rivers and features but few have extensive experience with the type and therefore their criticisms ring carry no weight with me. Granted, on paper, the 4140 steel 1/9 twist Wylde chambered barrels, commercial buffer tubes, non-HP/MPI bolt carrier, lack of barrel chroming, and other mil-spec departures may seem disappointing. But that's on paper. Shot for over SEVEN years before this review, RRA AR-15s (LAR-15s) have been stellar performers under hard TNP testing. The Elite Operator2 and Entry Tactical, wearing a few modifications of my own (discussed), achieved 1 MOA groups with STANDARD BALL ammo. With premium 77 gr Fiocchi Match Kings, the groups shrunk to 1/2 inch. Keep in mind these are tactical carbine variations of the LAR-15, not target rifles with overly thick barrels. Most high end AR-15s, piston or DI, have failed to achieve this accuracy. And this accuracy testing came only after many 1000s of rounds shot in TNP ...
