Bubbles in a fountain, and the dye?

Ok, so my friend and I want to put bubbles in our area source. But I wondered if adding the food coloring or something that could change the color foam? or think that is enough to create mess too much and dyeing of the source? too! What is the best type / brand of soap to use and how? It is a source larrrrrrrge. im not sure how big it is, its circular, perhaps up to 20 feet wide? thanks!

Lol it's great: D

As to the facts of styrofoam

What is EPS foam?

EPS polystyrene foam. Polystyrene is a polymer of styrene monomer, a liquid hydrocarbon that is produced commercially from petroleum by the chemical industry. At room temperature, polystyrene is normally a solid thermoplastic, but it can be melted at high temperature for molding or extrusion, then melted. Styrene is an aromatic monomer, and Polystyrene is an aromatic polymer.

History of styrofoam:
Polystyrene was discovered by chance in 1839 by Eduard Simon, an apothecary in Berlin, Germany. From estoraque, resin Liquidambar orientalis, which releases an oily substance, called a monomer styrene. A few days later Simon found that styrene was thickened, probably due to oxidation, a jelly called styrene oxide (Styroloxyd). In 1845 English chemist John Blyth and German chemist August Wilhelm von Hofmann showed that the same transformation of styrene was carried in the absence of oxygen. Metastyrol called their substance. Further analysis has shown that it is chemically identical to Styroloxyd. In 1866, Marcelin Berthelot correctly identified the training metastyrol styrene in a polymerization process. About 80 years passed before he realized that the heating of styrene initiated a chain reaction which produces macromolecules, following the thesis of German Hermann Staudinger Organic Chemistry (1881 to 1965). This eventually led to the substance receiving its present name, Styrofoam. The IG Farben company began manufacturing polystyrene in Ludwigshafen, Germany, circa 1931, hoping that this would be an adequate substitute to die cast zinc in many applications. Success is achieved when they developed a reactor vessel that extruded polystyrene through a heating pipe cutting production of polystyrene in the form of granules.

Characteristics of polystyrene:

Pure polystyrene is a colorless solid plastic with a flexible limited. Can be poured into molds in detail. Polystyrene can be transparent or may be required to take different colors. It is affordable and used for the production of plastic model assembly kits, plastic cutlery, CD cases, and many other objects where you want a fairly rigid, economical plastic of a different color.

The most common use of polystyrene, however, expanded polystyrene (EPS). Polystyrene spread is produced from a mixture of about 90-95% polystyrene and 5-10% of gas blowing agent, usually pentane or dioxide carbon. By use of heat, usually the mother, solid plastic foam develops.

The polystyrene foam used to contain CFCs, but other, more environmentally friendly blowing agents and safer now used. Because it is an aromatic hydrocarbon, it burns with yellow-orange flame, giving off soot.

EPS foam cutting:
Expanded polystyrene is very easy to cut with a cutter foam hot wire, which is easy to make a long and heated-wire, usually nichrome. The wire cutting foam works by heating the hot wire to the point where it can spray the foam close to it. The foam evaporates before touching the hot son, which produces cuts exceptionally smooth.
Polystyrene can also be cut with a traditional knife. To do this without ruining the sides of the blade of a diving first grass in water and cut with the blade at an angle of about 30 ยบ. The procedure is repeated several times for best results.
Polystyrene can also be cut, 3 and 5 axis CNC routers, enabling large-scale prototype and production models. polystyrene cup special are available that look more like large cylindrical rasps

Polystyrene Uses:
Polystyrene, shaped Cutting with foam and wire cutting system is used in models of architecture, signage current, amusement parks, plateaus film, the construction of aircraft, aerospace and more. These cutters can cost a few dollars (for a complete manual cutting) dozens of thousands of dollars for large machines that can be used in large quantities of industrial production.
