Just a word of warning: It is a federal crime to possess an unregistered molotov cocktail, or even to have all of the components of a molotov cocktail with the intent to make a molotov cocktail later.
The point being, all of the components are so commonplace that you should never talk like you're going to make one. I know one person who was convicted and sentenced to years in federal prison, even though he never actually assembled one, because he texted people that he was going to make one. Admittedly, in his case, he was also caught trying to assemble one. But the law didn't actually require that.
Edit: I forgot to mention the specific reason I recalled this is that part of the evidence against him was what he found by Googling molotov cocktails, like the meme says.
