What is the purpose of dry ice?

Dry ice is the solid form of carbon dioxide. It is used primarily as a cooling agent, but is also used in fog machines at theatres for dramatic effects. Its advantages include lower temperature than that of water ice and not leaving any residue (other than incidental frost from moisture in the atmosphere).

Why would you put dry ice in a well?

As the carbon dioxide (CO2) off-gases from the dry ice, the water becomes more acid, which dissolves some of the carbonate-based scale and lowers the bacterial count. The agitation of the bubbling dry ice in the borehole is also assumed to remove some particulate scale.

Does fracking a water well work?

In the water well industry, fracking can double the volume of yield in a well; in the oil/gas industry, fracking a well may be the difference between economic profit and loss. Geology: Liquids and gases move through the subsurface in either consolidated or unconsolidated rock material.

What happens to a wart when you freeze it?

If done carefully, cryotherapy poses little risk of scarring. If a wart is thick and requires extensive or repeated freezing, nerves around the wart can be damaged, scarring may occur, and the skin may take a long time to recover. There is a small chance of infection associated with cryotherapy.

How do I know when a wart is completely killed?
