Back when I was a freshman in college we were tasked by my, at the time Nuclear Engineering professor to construct a working bomb. Imagine our surprise - a teacher outside of highschool who enjoyed blowing **** up.
So I had the classic Tennisball with about 2000 strike anywhere match heads which I cut myself with a scissor. I couldn't jerkoff for about a week after that.
Others had the modified wine glass with everclear and gasoline - as if they needed an accellerant with that ****.
But by far the best 1 was the soda bottle with ALO, draino and h20.
The prof brought a fire cracker from Mexico that looked like it was taken from a tube of toliet paper, and finished off on the ends with a putty knife. We put these little fun seeking devices in the Boneyard Creek next to our lab at the University of Illinois.
All of ours went off without a hitch. But the soda bottle just floated away as if nothing was happening. The creek ran underneath our physics building - about 2 minutes later...
KABOOOOOM! The loudest single explosion i've ever heard at the time - sounded like a howitzer cannon at an Army Navy football game at Westpoint. 2 minutes later, the fire trucks start rolling, and they look at us, and they look at the teacher - shake their heads and drive away.

BTW, what is a Vaccum bomb? We talking like a fuel air bomb? or is it something else?
