In beaker A, you can see the oil and the water existing in separate layers. In beaker B, the beaker is shaken up, which disperses the oil in the water temporarily. When you set it back down again, however, (beaker C), you can see that it separates again. In beaker D, we added an emulsifier.
Why PI Was Created. PI was created to provide high school students a place where they can create their invention ideas. Too often, students conceive ideas that can change the world. Due to insufficient support and guidance, most high school students cannot bring their invention ideas to life.
Mr. PiBB was invented in the summer of 1972 after The Coca-Cola Company had the intention of creating a drink that would rival the growing success of Dr Pepper in Southern markets. After losing a law suit filed by Dr Pepper manufacturers who disputed Coke's original use of the name Peppo, Coca-Cola settled on the name Mr. PiBB for important brand-identification purposes.
