Comment Easy way to get antimatter in your garage (Score 2) 83
There's a very easy way to generate antimatter in your garage, basement or backyard. Heck, many people are probably doing it already without knowing it.
Go to Home Depot and buy a bag of potassium chloride water softener. Put it in your garage. There, you have antimatter. On a small scale you can do the same by buying at a grocery store a box of low sodium salt substitute, which also has potassium chloride in it.
If you don't believe me, take a Geiger counter and put it next to the bag of potassium chloride, and enjoy its clicking. I get around 60cpm, which is around 4 times the natural background in my location. Those are 511keV gamma rays resulting from the annihilation of positrons emitted by the K-40 isotope, which is a small but universal percentage of potassium anywhere in the universe.
