Florence Flask Was Preparing To Attend The Opera

In chemistry, a Florence Flask is a type of laboratory glassware with a round body and long neck. An Erlenmeyer flask (conical flask) is a type of laboratory glassware that is flat-bottomed and has a narrow neck. A joule (J) is a unit of energy which denotes the energy transferred to an object when a force of one newton acts on that object in the direction of its motion through a distance of one meter. A solution is a homogenous mixture of two or more substances. For this joke, a woman (Florence Flask) thinks she loses her jewels (joules) before the opera and asks her husband (Erlenmeyer Flask) to help her. He comforts her by trying to find the solution to her problem.
