The Extreme Diet Coke & Mentos Experiments
The Extreme Diet Coke & Mentos Experiments
Hanya sekedar mengingatkan kembali, ini bukanlah berita baru, tapi setidaknya untuk mengingatkan kembali akan berbahayanya jika hal ini terjadi kepada anak kita. Karena meminum Coke "Coca Cola" ditambah Permen "mentos" dapat bereaksi secara kimia, dan bisa berakibat fatal pada tubuh kita.
A Diet Coke and Mentos eruption, also known as a Mentos eruption or a Coke geyser, is a reaction of Diet Coke and mint Mentos candies. A two-liter bottle of Diet Coke, or of some other carbonated beverage, is used, although Diet Coke is preferred because it tends to react better. Dropping some Mentos into the bottle causes the Diet Coke to foam at a rapid rate and spew into the air. Mint-flavored Mentos are used, as fruit-flavored Mentos have a smooth coating which slows the reaction. Because of the spectacular nature of this physical reaction and the easy availability of the ingredients, the eruption is a popular subject for Internet videos. The bigger the bottle of coke the bigger the explosion.
A 2006 episode of the television show MythBusters[9] concluded that the caffeine, potassium benzoate, aspartame, and CO2 gas contained in the Diet Coke, in combination with the gelatin and gum arabic ingredients of the Mentos, all contribute to the jet effect.[10] In addition, MythBusters theorized that the physical structure of the Mentos is the most significant cause of the eruption due to nucleation. Mythbusters reported that when flavored Mentos with a smooth waxy coating were tested in carbonated drink there was hardly a reaction, whereas standard Mentos added to carbonated drink formed an energetic eruption, affirming the nucleation-site theory. According to MythBusters, the surface of the mint Mentos is littered with many small holes, allowing CO2 bubbles to form very rapidly and in great quantity, in turn causing the jet of foam. This was further supported when rock salt was used as an effective substitute for Mentos.[10]
A paper by Tonya Coffey, a physicist at Appalachian State University in Boone, North Carolina goes into detail on the reasons and physics behind the reaction.[11][12]

Thank's atas infonya sob
tapi kebetulan ak kurang suka juga sama soft drink
