Science Sunday: Generating Sparks

Post Author: Mark Dixon & Aoife Ryle

Today, we are making sparks without using any fire. How exactly are we going to do this? Through the use of metal and movement. When we smash the chrome spheres together very fast, they generate enough heat to burn a small hole through the paper placed in between them. Another way we can generate some sparks with only metal and no flames is by using slightly rusty ball bearings. The rust is iron oxide and the other ball bearing is wrapped in aluminum. By hitting the two together, we are creating a thermic reaction that creates that heat and spark. Click here to watch the full video.
