Making a simple hydrogen generator from a plastic bottle


Presenting another review on the manufacture of a hydrogen generator from a regular plastic bottle. This method can be called one of the easiest. Note that the material is for informational purposes only. We do not welcome the repetition of what we saw in home conditions.

Let's start with the author’s video

[media = https: //www.youtube.com/watch? v = ehQW9cguuCE]


We will need:
- plastic bottle;
- blade for hacksaw;
- wires with crocodiles;
- plastic tubes;
- glue gun;
- source of power.

The author of the idea uses a 9 volt Crohn type rechargeable battery. Let's get started.

First you need to break the blade for a hacksaw in the middle of the metal. It is more convenient to do this with pliers.

After this, you need to remove the bottle cap and make two holes in it for two parts of the canvas.

In this, you need to make another hole for the tube.

Now all this needs to be collected and fixed with a glue gun.


The generator itself is ready. It remains to take care of providing him with food. The author's power source is a battery, to which you need to connect wires with crocodiles.


The other ends of the wires are connected to pieces of cloth.

To produce hydrogen, you need to pour water into the generator and add a little baking soda.

As soon as we turn on the power, hydrogen evolution will immediately begin, which will exit the tube.

Yes, explosive gas is a very dangerous thing. It also explodes from compression, that is, detonates. Played with him for a while. Now, if you set fire to the tube here at the end, there will be a good boom)) You need to either pour water under the very throat, or let gas pass through the water barrier, then it’s safe.

A rattlesnake is not casual, when it burns - it rattles))
This will not be hydrogen, but an “explosive mixture” (two volumes of hydrogen per oxygen volume), “explosive gas” (since there is no water barrier, that is, it must be passed through another container with water) Very dangerous nonsense, ignites even from static voltage or simply getting into the atmosphere !!! Be extremely careful !!! Place the contacts as far as possible from the power source to the bottle so that when the power is turned off, the spark that appears does not inadvertently ignite the gas !!! It is also necessary to separate it from + by a partition, by - the terminal will be arr. be called hydrogen and oxygen + (oxygen to the atmosphere and hydrogen through the water barrier) !!!
