But how? Dogs are not clever creatures but they surely can learn well when trained with the right pace and methods. Take a look at this dog here that is working on the Archimedes’ Principle just to drink water from the tube container. Clever. Who knew dogs knew physics too? According to the principle, the volume of the ball is equal to the volume of the water displaced with the ball. Thus, when more balls will be placed inside the tube container, the water will be displaced to a greater extent and this is exactly what the dog did. Smart for sure.
