Last Lesson Shenanigans: Cork Cannons

Here’s a bit of fun for the last lesson of the year, with a sensible Chemistry or Physics class. The aim is to use the gas produced in the reaction between baking soda and dilute HCl (or vinegar) to propel a cork over a wall and into a beaker. Lots of fun with testing methods, hypothesising and problem solving.

Obvious safety issues: use low concentrations, keep washing hands and/or use gloves and keep goggles on at all times. Students must be sure to aim away from the body and each other.
