714. Which gas is used to show Clouds or Artificial smoke in film or Drama?

Fog is created by pumping one of a variety of different glycol or glycol/water mixtures (referred to as fog fluid) into a heat exchanger (essentially a block of metal with a resistance heating element in it) and heating until the fluid vapourizes, creating a thick translucent or opaque cloud. Devices specifically manufactured for this purpose are referred to as a fog machines.
An obsolete method for creating theatrical fog on-stage (although the technique is still commonly used in motion) is to use a device known as a thermal fogger, initially designed for distributing pesticide, which aspirates a petroleum product (typically kerosene or propane), ignites the fuel, and then mixes in air and pesticide to create a dense fog. For theatrical purposes the pesticide is typically replaced with glycol, glycol/water mixtures, or water. This technique is similar to the smoke generators used by militaries to create smoke screens, and is generally only used outdoors due to the volume of fog produced and the petroleum fuel required.
Some use liquid Nitrogen.
 
708. What is Blood Doping?

Blood doping is the practice of boosting the number of red blood cells in the blood stream in order to enhance athletic performance. Because such blood cells carry oxygen from the lungs to the muscles, a higher concentration in the blood can improve an athlete's aerobic capacity and endurance.
 
707. What is Ice Circles?

A rare phenomenon usually only seen in extremely cold countries, scientists generally accept that Ice Circles are formed when surface ice gathers in the center of a body of water rather than the edges. A slow moving river current can create a slow turning eddy, which rotates, forming an ice disc. Very slowly the edges are ground down until a gap is formed between the eddy and the surrounding ice. These ice circles have been seen with diameters of over 500 feet and can also at times be found in clusters and groups at different sizes.

702. What is Supercells?

Supercell is the name given to a continuously rotating updraft deep within a severe thunderstorm (a mesocyclone) and looks downright scary. They are usually isolated storms, which can last for hours, and sometimes can split in two, with one storm going to the left of the wind and one to the right. They can spout huge amounts of hail, rain and wind and are often responsible for tornados, though they can also occur without tornados. Supercells are often carriers of giant hailstones and although they can occur anywhere in the world they’re most frequent in the Great Plains of the US.
