Why Real Explosions Don't Look Like Movie Explosions

The most notable difference between a Hollywood explosion and a real explosion is that a movie explosion does not kill the protagonist. That's a given. We've seen how our heroes can casually walk away from explosions without even feeling the blast force -and it looks good because of the bright flames behind them. And that's the next difference- those colorful flashes do not happen in most real explosions of the same size. Nuclear bombs may be the exception here. Tom Scott shows us what's done to make them look so appealing. (via Digg)
