Description: The famously dramatic elephant toothpaste chemistry experiment! A conical flask containing a cute purple elephant, and overflowing with foam which has a toothpaste style stripe. The experiment demonstrates a chemical reaction involving hydrogen peroxide, washing up liquid and a catalyst e.g. potassium iodide solution or yeast, which produces a sudden expanding foam full of bubbles of gas. The molecule 2H202 and the resulting 2H20 and 02 molecules are represented in the image.
Description: In the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.
