The speed at which a reaction occurs (a.k.a. the reaction rate) is affected by conditions like temperature, reactant concentration, reactant surface area, and the presence of a catalyst. Explosions are examples of reactions that occur very quickly because the right conditions are present for the reactants to combust rapidly. In this activity, students will design and 3D print a shaker/filter that will deliver a reactant with the correct concentration and surface area for a small dust explosion to occur. The use of 3D printing allows students to design and modify filter prototypes quickly and accurately - enabling students to try different shapes and sizes that could not have been tested using conventional materials such as cardboard and filter paper!
