Here's another example of how the government plays you like a chump with the brain of a 11-year old:

take a look at that mushroom cloud. What's it make of? Gas? Is that right, it's made of gasses? Where do they come from?

When you detonate TNT every gram produces 1L of gas. TNT is a chemical compound that expands into gas creating the force that blows you up.

What about nuclear weapons? Do they expand into gas? Or do they just shoot out death rays?

There's nothing expanding in a nuke. It's fission, releasing energy in the form of gamma rays. There should be no mushroom cloud. There would be heated air but you can see from your oven that heated air doesn't turn into billowing clouds.
