![]() Professor Miller reached thousands of students in the course of his nearly 40-year teaching career, and inspired millions more throughout North America and Australia via television programs like The Mickey Mouse Club and Miller’s own show entitled Why Is It So? His love for science is indeed infectious, as you can see in this segment about the shock value of capacitors. He was completely fascinated by physics, and deeply desired to understand it as best he could so that he could share the magic with people of all ages. Professor Miller’s was a shouting, leaping, arm-waving, whole-bodied approach to physics demonstrations. Imagine if Cosmo Kramer were a physics professor, or if that doesn’t give you an idea, just picture Doc Brown from Back to the Future (1985) with a thick New England accent and slightly darker eyebrows. His demonstrations are dramatic, delightful, and about as far away from boring old math as possible. In pictures, his stern face commands respect. Professor Julius Sumner Miller was energetic and enthusiastic about physics to the point of contagiousness. And while it’s true that the student must be willing to learn, having a good teacher helps immensely. The fun is in the hands-on learning, the lab work, the live action demonstrations of Mother Nature’s power and prowess. YouTube.Let’s face it - for the average person, math and formulas are not the most attractive side of physics. ![]() ^ Archived at Ghostarchive and the Wayback Machine: How to Crush a Can Using Chemistry."Professor Julius Sumner Miller maintains his faith in physics despite Why Is It So? near-miss". Madison, WI: University of Wisconsin Press. : CS1 maint: multiple names: authors list ( link) "Reinterpreting Popular Demonstrations for Use in a Laboratory Safety Session That Engages Students in Observation, Prediction, Record Keeping, and Problem Solving". Alternatives Īddition of sodium hydroxide to a can filled with carbon dioxide can produce a similar result. Nevertheless, Professor Julius Sumner Miller could make a steel drum collapse by sealing the opening of the drum after the water inside the drum boils and pouring water and ice onto the drum surface. Unlike other stronger can such as steel can, the aluminum can will be collapsed before the water can be drawn inside the can. As a result, in a basic demonstration, only an aluminum can is able to be used since it is not very strong. There will be an impeding event that could occur which is water in the water bath being drawn inside the can by the reduced pressure. The condensation of water reduces pressure inside the can, so the higher pressure outside the can makes the can collapse. ![]() Then, inverting a water vapor-filled can into a water bath causes the water vapor to rapidly condense back to liquid water. As the water is boiled, water vapor is created and fills the space inside the can which then pushes the air out. The demonstration starts with boiling water inside the can. ![]() Due to the low pressure inside a can as compared to the pressure outside, the pressure outside exerts a force on the can causing the can to collapse. Collapsing can or can crusher experiment is a demonstration of an aluminum can being crushed by atmospheric pressure.
