I will keep this short:
I am writing a story about a Society with lots of Superheroes, and I want them to discover that they have powers after inhaling some sort of chemical. I want this to be pretty scientific based, not just saying magic or anything. They don't have powers before, they inhale it, they have powers shortly after. What could possibly do that? Based on what I know, I was thinking an Aerosol Can of stuff that uses CRISPR to replace the subject's DNA with upgrades.
With the DNA of the powers, I understand that having powers like fire doesn't make sense with normal DNA, so there is leniency there, or "magic". Assume that each person has a set power they could get, and they CRISPR changes the DNA to "unlock it". I just want what it take for the CRISPR Method to be used in Aerosol form.
