I once did a guest post for Prepography about prepper related things I learned while working in a prison. Today’s post is another tip I learned from a felon.
While digging through the Martha Stewart website doing research for an entrepreneur class I was taking I saw her give a tip to use beads of latex calk every 6 inches or so along the edges of a run to make it non-slip.
Since my wife loves rugs, and I hate them bunching up and slipping, but hate to buy those expensive no-slip mat. This works well, never think you cannot learn something from convicts… (more…)
One of the things I like best about running this website is all the cool people I get to talk to and learn from. The other day I was talking with YouTube personality Katzcradul and she informed me about Paul Gautschi and his wonderful film Back to Eden. I won’t go into detail here (except to say you really ought to watch the film), but I did learn about the importance of mulch, and decided to follow his method this year. (more…)
I needed some limestone to work some cement experiments trying to replicate both the Portland cement patent, and to make slaked lime for mortar mix.
This meant I had to be able to identify limestone. Luckily since limestone is calcium carbonate, ( a base). Simple chemistry ensures that when it makes contact with acid it will fizz (which is CO2 being released) as the acid and the base attempt to counteract each other.
If you have a large weathered rock, you may get better results if you smash it into little pieces – limestone is brittle and crushes well.
Then simply drop some strong vinegar or weak muriatic (hydrochloric) acid on the rock. If it fizzles, then it is a good bet its limestone.
