Ah! Rapaire!

Did you ever build a 'rocket gun'? Take a piece of pipe sealed at one end - plastic or water hose was considered 'safer' - ha! - and mount on a piece of board with a handle. Get the tiny 'penny' rockets which had no stars inside, and Voilà! instant bazooka!

Take 2 bolts and one nut, cut off the heads of many matches, place powder in the space left by assembling the contraption, tighten - NOT TOO BLOODY TIGHT! and Throw! Grenades!

Never did me any harm...

Hmmmm, just going to count my eyes, ears, fingers and toes again...
