I've been to Six Flags many times since I've lived in St. Louis for years and would probably give them a better review but if someone went on just this day without season passes, they would likely not return so with that visit alone I would have given them two stars.
Elephant toothpaste reaction. Elephant's toothpaste is a foamy substance caused by the rapid decomposition of hydrogen peroxide. This is often used for classroom demonstrations because it requires only a small number of ingredients and makes a volcano of foam.
Sensodyne is a brand of toothpaste that was first sold by Block Drug, a Brooklyn, New York-based company established in 1907 by pharmacist Alexander Block. The toothpaste was first marketed in 1961 as a desensitising toothpaste based on a strontium chloride formulation. In 1980, Sensodyne launched a new toothpaste containing potassium nitrate, a mild local sedative. In 2000 Block Drug was purchased by GlaxoSmithKline. In 2006, Sensodyne Pronamel was released and is marketed as a toothpaste that protects against the effects of dental erosion.
