Once I had the idea in my head I used the advice from the How to Make a $1,000 a Month Business course and validated it by seeing if anyone would be willing to buy my product before I invested any time or money into it.
Interesting facts Argon is created when the potassium in the earth's crust decays. It's the most abundant of rare gases. It emits light when electronically excited. About .94% of the earth's atmosphere contains argon.
That's right, argon (Ar) makes up a little over one percent of our atmosphere. Lord Rayleigh and Sir William Ramsay discovered and isolated argon gas, but we joke about how long it took. They could never have done it earlier, because the technology wasn't available. We say that today's scientists are on the cutting edge and discovering elements that will have atomic numbers over 120. A century ago, techniques used to discover argon were on the cutting edge.
