See this is what happens when you stop having nuke drills in school. Kids these days think we will do anything other than get vaporized lol. Duck and cover mother fucker.
The duck and cover thing does two main things. First, it helps to protect you from debris that would kill you when the bomb itself wouldn’t. Secondly, the most important thing is to give you the false sense of security in knowing what to do.
If you are within range of the blast, just enjoy the show after the flash because it will be a once in a lifetime sight.
