video Mini Hydrogen gas generator
Hi !
In this instructable i will show you how to make simple HHO Generator with house hold items.

Items needed..
*Jar with cap
*2 stainless steel nuts
*4 Stainless steel bolts
*polytoobing
*2 stainless steel plates
*Tape
*Salt
*Water

Tools needed
*Saw
*Hotglue gun
*Drillpress

Step by step in video if cant understand something dont be afraid to ask!

I would be the most careful about the Chlorine gas this method produces.

I´d prefer another electrolyte (NaOH e.g.)

Process of electrolysis[edit]

The key process of electrolysis is the interchange of atoms and ions by the removal or addition of electrons from the external circuit. The desired products of electrolysis are often in a different physical state from the electrolyte and can be removed by some physical processes. For example, in the electrolysis of brine to produce hydrogen and chlorine, the products are gaseous. These gaseous products bubble from the electrolyte and are collected.[3]


2 NaCl + 2 H2O → 2 NaOH + H2 + Cl2

What wold this be used for

how did you make the thing on the cap?

dont we need electricity?? could you make it more precise?
By using an electrolyte and putting a spontaneous redox reaction to work, no electricity is needed. However, the amount of gas generated will be marginal in the setup described.
**If using a metal that reacts appropriately with the electrolyte. Otherwise, you do have to use current.

Salt water forms chlorine gas in higher concentrations.best be careful using salt baking soda is a better choice all your doing with the salt is making the water more conductive

How much salt and water do you mix ?

More u use better effect ,but make sure than water is very concentrated with salt so you can fast'n effect.
Nice quick project. Make sure you run the output through a bubbler or some sort of backflow spark arrester. If you generate a decent amount of HHO and spark it off you have a nice little bomb. Ask me how I know. ;-)

Okey ! I will be wery careful when test this :D
Against thanks for your replays!!
