Simple Mini HHO Generator!




About: I've been with Instructables for over 3 years now, and I'm loving it! Thanks to everyone who's supported me by giving feedback. It means a lot. If you have any questions please feel free to send me a message.

Today I will show you how to make A great output HHO generator for under 5 dolllars!

Step 1: Get the Stuff

You will need the following: A 9 or 12 volt wall charger (can be found at any thrift store. Make sure it is A DC power supply) A 4" tall airtight pill bottle. fish tank or oxygen tube. Two bolts measuring three inches long and four nuts to fit on them. Epoxy (optional). Electric tape. A drill and 2 bits, one the same size as both bolt and one the same size as the fish tank tube. Distilled water and baking soda.

Step 2: Drilling...

Drill three holes in the cap of the medicine bottle in the same places shown above in the picture. Be careful not to crack the lid!

Step 3: Screwing...

Before doing anything, screw A nut onto each bolt. Next, Screw the two bolts in the holes directly across from each other and make sure that they are not touching at all. Now screw in the remaining nuts, one to each bolt. These are to keep the bolts in place. In that extra hole above both bolts, squeeze the fish tank tube in. It should be A tight fit. Blow on the fish tank tube awE little bit. If you hear any air leaking, put some epoxy on the seams of the screws and let it sit for 24 hours.

Step 4: Stripping and Taping...

Take the 9 or 12 volt wall charger and strip both wires. Now wrap one wire around one bolt, and the other wire around the other bolt once again making sure that the bolts and separate wires are not touching . Now tape the wires to the bolts. Don't use anything over 12 volts.

Step 5: Solution Dilution...

To make the simple electrolytic solution, fill the bottle 3/4 the way fulland add half A teaspoon of baking soda. Mix for about 15 seconds.

Step 6: Make a Highly Explosive Gas Using Water!

Screw on your modified cap and plug it in. To make A bubbler to collect the gas and to help prevent your HHO generator from exploding, pimply fill A paper or plastic cup, not glass, with water and A few drops of soap. Stick the fish tank tube in the bottom of the cup and small HHO bubbles will float to the top and collect together. This amount was collected at 12 volts in 20 seconds. Always wear safety glasses and ear protection when your are making and using this gas. And it is probably A good idea to have A fire extinguisher on hand. From here I am not responsible for what you do with this explosive gas, so please be careful! Dont forget to leave comments! Thanks for reading.

    Detonating gas is really dangerous. Hence the name. Better collect just the hydrogen part. When you light this up, it still will burn with great power. But it won't explode.

    Back in school (must be 40 years or so ago) we had a young chemistry teacher. He made a balloon filled with detonating gas. That time we had the little straws for school milk wrapped in thin paper which, when rolled to a string and lighted was permanently glowing (It must have been soaked with saltpeter or something; don't know). Anyhow, this was excellent as blasting fuse. So the ballon climbed to some 50 meters or so before it exploded. Man - this was really loud. I definitely would not like that going up nearby.

    But I like the big boom when I light the two gases combined! :'{

    have seen the balloons done with oxy/acetylene too(youtube hi-jinks ensues. Not for the feint hearted, or those lacking bail money).

    Given the tiny, unconstrained volume of gasses being produced here, you needn't worry too much about the "explosion" bit of it. By the time you make enough gas mix to be dangerous to more than your eyebrows, the bubbles will have popped and released the gasses into the atmosphere where dilution resolves the danger for us.

    That being said, safety first. Whenever playing with flammable stuff, safety glasses and a nearby fire extinguisher are always a good idea. And maybe a GFCI outlet to plug the power supply into... just in case.

    Yes. Producing enough gas is not that easy. However, safety glasses are a great must and unless you want to become deaf or like to bleed from your ears a good pair of ear mufflers is much recommended! Wearing gloves and not burning clothes are also some paraphernalia you will not miss in the eventual case.

    That is true. I've made the change. It is interesting how one of the most powerful gases on the planet can be made from one of the most abundant resources on the planet.

    way back when I was in junior high ...after learning about this wonderful method of turning simple h2o into something a little bit more exciting..I spent 2 months collecting the stuff in a Mason jar and transferring it into a mylar ballon... then I hung the ballon from a tree with one of those model rocket igniters stuck in it and about 100 or so feet of cord.... " we lived in town" when my parents were away I touched the thing off.... huge fire ball and I can still remember how the windows did that shake thing...Lucky for my 14 year old self they didn't break...the cops circled the block for an hour or so... the neighbors were confused... and I never said a word...I didn't even know what the stuff was called at the time... never made it again. But man, what a blast from a small balloon.
