Dad`s not much of a rocket scientist

Building model rockets and can be a very enjoyable father and son bonding project.
While doing some pre-flight diagnostics everything seams to be going well but according the poster "My father needed to test the ability of the black powder charge to eject the back section of the rocket. Needless to say, i think it worked".
"Jesus! JEEZ. Oh m' word." is right, you almost built yourself a new face!
