I saw this excellent diagram in another thread, and it got me thinking. Is the huge mushroom cloud from the cookie bomb really appropriate?
My point is, you can see that the cookie has significantly less explosive power than the FAB5000, yet shares the same effect.

Another question, kind of related. The scale along the bottom where it reads "blast velocity m/sec" starts at 280, and goes DOWN to 28. Isn't this kind of against the conventions of graphing, or is it just a typo?
