Rubens Tube
Always a class pleaser when I demonstrate the Rubens tube. Even more fun when we link it up to a student's phone, and they play their favourite soundtrack. Explaining how it works demonstrates how sound travels through the air much better than other ways of teaching.

When making up solutions - why is the temperature so important. Students made up a solution of NaOH to the correct molarity, then after cooling, they saw that their perfect solutions weren't so perfect after all. Lesson Learnt.
