Experiments of forcing water by ayer compressed.

Let there bee a large pot or vessell, hauing at the side a peece of wood made hollow, hauing a clacke of leather with a peece of lead upon it, within the vessell also let there be a pipe through the top of the vessell, reaching almost to the botom of it: at the top of which let there be a round hollow ball, and on it a small cocke of brasse. Note that if you fill the said vessell halfe-full of water, and blow into the hole of the pipe, at the side, your breath will lift up the clack, and enter the vessell, but when it is in, it will presse down the clack: blow into it oftentimes, so shall there bee a great deale of ayre in the vessell, which will presse so hard upon the water, that if you turne the cock at the top, the water in the vessell will spin out a good while.

Another.

Let A, B, C, D, be a great vessell, having a partition in the middle: let there bee a large tunnell at the top of it, E, F, whose neck must go into the bottom almost of the lower vessell: let there be a hollow pipe also coming out of the partition, and almost touch the top of the upper vessell. In the top of the upper vessell let there bee another pipe, reaching from the bottom of the upper vessell, and extending it selfe out of the vessell a good way: let the top of it hang ouer the tunnell. In the top of the upper vessell let there be a hole besides, to be stopped with cork, or otherwise: when you will use it, open the cork-hole, and fill the upper vessel with water: then stop it close againe, and poure water into the tunnell, and you shall see that the water in the upper vessell will run out of the pipe into the tunnell againe and so will continue running untill all the water in the upper vessell be run out. The reason thereof is this; the water in the tunnell pressing the ayre in the lower vessell, maketh it ascend the pipe in the partition, and presse the water in the upper vessell, which having no other way but the pipe, it runneth out thereat.

The forcing of water by pressure, that is the naturall course of water in regard of its heavinesse and thinnesse, artificially contrived to break out of what image you please.

Let A, B, C, D, bee a cestern placed upon a curious frame for the purpose, let the bottom of this frame be made likewise in the form of a cestern: Through the pillers of this frame let there passe hollow pipes from the bottom of the upper cestern, and descend to the bottom of the lower cestern, and then run all to the middle thereof, and joyne in one, and turne up into the hollow body of a beast, bird, fish, or what your fancy most affecteth: let the hole of the image whereat the water must break out, be very small, for so it will run the longer. Fill the upper cestern with water, and by reason of the weight thereof it will passe through the pipes, and spin out of the hole of the image.
