Practicing for his engineering test, Treb has to measure and match weighted blocks. Treb best remembers the law of balances when picturing fruit. Apples are among the heaviest fruits, but equate to that of a couple of cherries or a few blueberries. Treb borrows a scale from one of his classes and applies his fruit theory. He found balancing cherries and blueberries was difficult due to their small circular nature, but nonetheless equated the scale. He feels confident in his test after confidently balancing various fruits in various combinations.
