So is it possible to make a powerful heater using Lego, that doesn’t also melt the Lego? It’s winter here in Ireland, and cold, so in this video, we’ll experiment with generating heat, and trying to protect our Lego from melting.

Nichrome wire is a type of wire that has a very high resistance. When we pass significant current through it, it generates large amounts of heat. This is what is often used in toasters and heater elements. Let’s see if we can build a heater fan using Lego and nichrome wire!
