Hello my dear friends! Roman is here with you as usual! In today’s video I’d like to show you how to make a small hydrogen generator with ten razor blades.

Firstly, we need power supply unit for 5-12V and from 0,5 to 2 amp of strength of current. Then copper wires, a glass jar with the airproof screw lid, plastic bottle, a piece of plastic ruler, two droppers, ten razor blades, and a simple salt. As for tools, we need a solderer, a glue pistol and a stationary knife.

Let’s get the work started, and first of all, blanch the edges of the blades.

We have to get such semi-products. Then we set them on the ruler. Note that distance between the blades should be minimal, but the blades shouldn’t touch one another. You don’t need to leave much space between them too as it will require a heavier power supply.
