Firing the 12 pounder Coehorn [video]
« on: September 20, 2011, 02:28:40 PM »
The day we fired the wheeled soda can mortars, we shot this too.  Ammo used was 4-1/2" PVC filled with cement with 600 grains of  BP.  This thing is very loud with 600 grains and projectile.

     Nice smoke trail to illustrate the trajectory, Dom.

 Looks like a little KNO 3 + C 12 H 22 O 11  action there, eh?

Smokin' my pipe on the mountings, sniffin' the mornin'-cool,
I walks in my old brown gaiters along o' my old brown mule,
With seventy gunners be'ind me, an' never a beggar forgets
It's only the pick of the Army that handles the dear little pets - 'Tss! 'Tss!

From the poem  Screw-Guns  by Rudyard Kipling

KNO3 is potassium nitrate (the oxidizer) and

C12H22O11 is sucrose (table sugar.)  It is a mixture commonly used as home brew solid rocket fuel and produces a lot of smoke.

I think so.  I'll ask him this afternoon.   To see a rocket in action, just youtube search "sugar rocket".
