Here’s another super simple experiment that almost seems magical but it works because of air pressure Even though most of the time you can’t see or feel it the air around us is pushes against every surface But by following the instructions for this science experiment you can watch as the plastic bottle is crushed read more experiment phosphoric acid will be used as the catalyst The excess acetic acid will be quenched with the addition of water The aspirin product is not very soluble in water so the aspirin product will precipitate when water is added The synthesis reaction of aspirin is shown below

The Cold Crushing Strength CCS represents the ability of a product to resist failure under compressive load at room temperature It has an indirect relevance to refractory performance and is used as one of the indicators of abrasion resistance The higher the CCS of a material is the greater should be the resistance to abrasion Refractories with high CCS are also expected to have higher Crush Can Experiment Upon completing this experiment I observed that when chilled water is poured into the can it would crush and lose shape My hypothesis was not supported The pop cans Water Heat Experiement Empty soda cans Stove Cooking tongs Gloves Bowl Cold water Ice cubes
