Dihydrogen Monoxide Projectile Weapons

Be prepared to fend off airship pirates or even the dreaded air kraken!


Mod some cheap water guns to give them a steampunk look with little more than paint.

Step 1: What you'll need

We found some cool water guns for $10 at Walmart but we weren't happy with the Super Soaker colour scheme.

To give the guns a bit more style you'll need:

• Primer or spray paint for plastic
• Acrylic craft paints (black, brown, silver & bronze)
• Spray on clear coat or sealer
• Paintbrushes
• Sandpaper
• Drywall compound
• Masking tape
• Scraps of pleather and interesting plastic bottle (optional)

You fool!! Don't you know that Dihydrogen monoxide is deadly when inhaled?! Hundreds of people die every year from breathing dihydrogen monoxide! lol

[peldrake]

That's hillarious. Actually, in my science class last year, we had an article going for the banning of Dihydrogen Monoxide that we were supposed to evaluate or something, and more than half the class (granted, we were 7th graders, but still, it was an advanced class) thought that the argument was reasonable! I was one of the select few who got the joke. But, your comment reminded me of that. Here is an abreviated version off wikipedia: "Dihydrogen monoxide:

is called "hydroxyl acid", the substance is the major component of acid rain.
contributes to the "greenhouse effect".
may cause severe burns.
is fatal if inhaled.
contributes to the erosion of our natural landscape.
accelerates corrosion and rusting of many metals.
may cause electrical failures and decreased effectiveness of automobile brakes.
has been found in excised tumors of terminal cancer patients.

Despite the danger, dihydrogen monoxide is often used:

as an industrial solvent and coolant.
in nuclear power plants.
in the production of Styrofoam.
as a fire retardant.
in many forms of cruel animal research.
in the distribution of pesticides. Even after washing, produce remains contaminated by this chemical.
as an additive in certain "junk-foods" and other food products."

(Wikipedia, http://en.wikipedia.org/wiki/Dihydrogen_monoxide_hoax). Just search dihydrogen monoxide hoax in google and you'll get the entire hoax, but just to give you the idea, look up! For those of you who don't know what direction "up" is, ^. I even cited it! YAY! All right that seems to me like quite enough typing so, >CONCLUSION!<

[Father Christmas]

Drowning is nothing to lol about. lol

[geterkikzkid]

Put in a bit of Pure Dihydrogen Dioxide, and that'll do a number.

I wouldn't really recommend it, and I won't be responsible for any occurrences if you actually do.

[JerBear]

H2O2 is hydrogen peroxide.

[ololol]

are you kidding me? -.-

[indestructibleguy]

would putting a little bit of dry ice in the bottle increase the blasting range? (but only for those that can be pressurized until you pull the trigger...)

[Playa2ne]

You might try using a C02 cartridge for a bb gun instead, for a booster. I highly advise against using dry ice. I have seen it blow up metal containers when mixed with water. You could get seriously hurt.

[Lentamentalisk]

Absolutely not. Putting dry ice in it will cause it to explode. There are no squirt guns that can contain the pressure. Dry Ice is solid CO2, which has a vapor pressure of 830psi. Plastic soda bottles have been safely tested at around 100psi (depending on the brand) but almost all of them shrapnel by 140psi. DO NOT USE DRY ICE check out the following video at about 2:25 for what happens when you put dry ice in a water bottle: http://dsc.discovery.com/videos/time-warp-dry-ice-bomb.html

[indestructibleguy]

awesome!! what metal could I use that would hold that much pressure? the whole gun would have to be metal. and would it blow me back when I pulled the trigger?

[cioeboy]

Look for paintball parts. Because they use CO2 tanks (and some higher pressure compressed air tanks) most of the parts are rated for those kinds of pressures.

[hear the reaper]

btw if u wanted to diy it ... you could use an old barbeque industrial gas can .. those things can take mad pressure .. my granads back burned and only blew the crappy plasticy top off it .. :) .. they can take a tonn .. i think is up too 1000 .. but dont take my word for it bro ,, im only guessing cuzz there tempered steel bro .. seriously .. dangerous bro .

[Lentamentalisk]

No. Those gas grill cans are only designed for propane, so are probably safe up to about 300psi. Yet again, dry ice is not safe.

[Lentamentalisk]

Look for parts at McMaster Carr http://www.mcmaster.com/ Any pipe that specifically says 2000psi or higher will work. Remember however, that the system is only as strong as its weakest joint. That means that if you buy 19 of the 20 pieces rated at 2000 psi, but you can only find a valve rated at 150psi, the entire system is only safe to 150psi.

[squirrelnuts]

VARY COOL!!!!!!!!

[Ian Cognito]

That's not a DiHydrogen Monoxide weapon, it's plainly either an Oxygen DiHydride weapon or a Hydrogen Hydroxide weapon!!!!!

[beer694]

im sure u were trying to sound smart but dihydrogen monoxide is just simple h2o or water

[geewizartcool]

the point of steampuunk props is to make them appear complicated and use archaic language to describe them as victorians would have. water guns="Dihydrogen monoxide projectile weapons."

[prop master]

i think thats kinda the point she used water guns

[cheeseandbroccoli]

pretty cool. nice job

[electfire]

nice- btw love the name- sounds a lot more oninious and sciencey most people dont know that water can be called Dihydrogyn Monoxide (Di = 2, mono =1) and water is H2O-

[Wasagi]

Nice!!

[chamunks]

Oh man DiHydrogen MonOxide Lmfao Oh man penn and teller do I ever love you're hatred for hippies. I mean... Did I say that out loud?

[Sam Cook]

Nice job. It looks a little bit like one of pistol grip nozzles that we had in a volunteer firedepartment I was in once.

[dark sponge]

That stuff is deadly! You need to include some information on how to stay safe when using chemicals like this! http://www.dhmo.org/

[hoihoi151]

dihydrogen monoxide is another name for water.

[dark sponge]

It was a joke, I know basic chemistry :-)

[dombeef]

But it is still deadly

[Kryptonite]

:D

[Kryptonite]

Then why are we making a gun which can shoot this!?!

[Arano]

Nice title. It reminded me of something that happened at the school i was... Someone told he placed a dihydrogen monooxid bomb somewhere in the building and the school got evacuated... that was a nice day

[Lensman01]

I am so glad that people are waking up to the dangers of Dihydro Monoxide. Apart from the obvious dangers of inhalation, it should also be noted that it behaves dangerously at all temperatures, especially when combined with motor vehicles. Perhaps the worst or most offensive danger is the unsavoury and unsanitary behaviour of piscines which make their home in this environment.

[Kaelessin]

:D very awesome indeed! I love the idea you had there with the green water bottle . . .it looks like old fashioned glass in the photos!
