When you open up the front door, this is what you're looking at. It's pretty simple. It's a hole in the ground.

The marriage could not be consummated and the only option was to take me back 'ngansing baa' open my vaginal orifice.

The kinetic energy of flowing water and the potential energy of a head of water was converted into rotational energy by a water wheel.

Like a hole in a dam, once pent up pressure began to escape, it widened the opening and tore apart the system.

The angle of the toilet pan is not steep enough, or the pipe that connects the pan to the pit is not sloped properly, or the pit collapses on its own weight.

Tom caught some bugs and put them in a jar. He then punched a hole in the lid of the jar so that the bugs could breathe.

Bacteria may escape from the phagosome before the formation of the phagolysosome Listeria monocytogenes can make a hole in the phagosome wall using enzymes called listeriolysin O and phospholipase C. Killing Bacteria have developed several ways of killing phagocytes.

But a pinhole, the mother of all analog cameras, requires much more than that a good dose of patience and concentration, for a start, but also an understanding of the basic principle of photography, which is controlling light.

So one of my graduate students, John Scannella, looked through our whole collection and he actually discovered that the hole starting to form in Triceratops and, of course it's open, in Torosaurus so he found the transitional ones between Triceratops and Torosaurus, which was pretty cool.
