Visit From The Police Over Backyard Ballistics

Okay... I just spoke about 300 words per minute to two policemen trying to explain that the boom was some fun experiment that my boy and I have been doing.  I said, "You know the book 'Backyard Ballistics'?  I mean I have this son that is yay high and we have been doing little experiments and this one... well I took a banana and stuffed it in the pipe... and it really went kaboom...  We're just playing.  And we are doing this science fair experiment with solar panels.  Shooting rockets.  You should see the house.  We're like crazy science people... Like NASA!"  He said, "So you were making a pipe bomb?"  I said, "No!  It was a banana from the compost bin.  I didn't know it was going to work so good.  I mean it is gun powder.  I know.  I won't do that anymore.  Most are just poooooof.  You know?"  He said, "You know your side door is open?"  I said, "That's for the dog."  He said, "Okay, we'll just write this one up as a science fair project experiment."  I said, "Okay, sorry."
