How to make Rockets for the water.
The diameter of hollownesse of the mould for Rockets that swim on the water, must be one inch, and eight inches long: let the breech enter into the body of the Rocket one inch, and it must have no broach at all in it. Let the diameter of the thicknesse of the rowler bee three quarters of an inch, the rammer must be a thought lesser; then ram it full of the composition of Rockets for the water; joyne to the upper end of it a Saucisson: then couer it all over with melted pitch, rosin, wax, or tallow, to the end that the water may not spoyle the coffins; and to make it float along the water, binde a rod about two foot long, as you did unto the rockets for the ayre: now if you would have the rocket to change his actions, (that is, to swim one while above the water, and one while under the water) then put into it in the filling, one spoonfull of composition, and ram that in; then one spoonfull of whole powder, and ram that in; and then another of composition, and after that another of whole gunpowder, so do untill you have filled it quite. If you would have it change colour, then shift the composition divers times, (that is, put in one spoonfull of the composition of rockets for the water, then another spoonfull of the composition of rockets for the ayre, or rochpeter and gunpowder mixed) untill you have filled it.
How to make a Rocket that shall burne a good while in the water, and then mount up into the ayre.
First you shall make a rocket for the water, and binde unto the lower end a stick about two foot and a halfe long, having a large hole in the end thereof: then tie unto it (but loosly, so that it may easily slip out) a rocket for the ayre, and let the stouple that primeth for the rocket for the ayre, enter into the breech of the water rocket, then let the end of the rod of the rocket for the ayre enter into the hole of the rod of the rocket for the water: besmeare then both the rockets with tallow, grease, or wax, or any oyle colour that the water may not spoyle the coffins of the rockets; then hang a stone at the bottom of the stick that hath the hole in it, to make it sink down into the water; then fire the water rocket, and cast them into the water; the fired rocket will burne in the water, and being consumed, will giue fire unto the other rocket, which being loosly tyed, will slip the bond, and mount up into the ayre. This is represented by the figure G, G. The floating rocket mentioned before, is expressed by the figure noted I, K.
The description and making of two sorts of fire bals for the water.
For to make the first, you must make a ball of Canvas, about the bignesse of a Foot-ball, or bigger if you please, and fasten in it a double Rocket for the water: if you will, also you may stuffe the rest of the ball with the composition that will burne under the water, and cut holes in the sides, and therein fasten other bals, and petrards in them: then cover the ball over with Tallow, Pitch, or painting, except the place where the Rocket is primed, and it is done. It is represented by the figure noted with A, and it will tumble up and downe in the water.
