The video tutorial explains how to make an electric fuse using ping pong balls, which are flammable due to their nitrocellulose content. The process involves creating a slurry with acetone and ping pong balls, mixing it with black powder, and grinding it to a fine consistency. The ping pong ball acts as a plasticizer and binder. The tutorial also covers making a detonator using steel wool and a 9 Volt battery. The final demonstration shows the properties of the mixture, referred to as 'Black Mom', and its quick-drying nature.
