Introduction: BREATH UNDER WATER!!!!!!!!!!!

Picture of BREATH UNDER WATER!!!!!!!!!!!

this is my first instructable so I want to start of with somthing easy for me and easy for your so if I make any mistakes please comment remember I will update this instructable come summer time.

In this Instructable I am going to show you how to make an under water breathing device (didn't know what to call it but I like to call it Sam as in Sammy the fish) the device allows you to breath under water for a shorter time but you can't use it very long and I suggest you always swim with a friend in case !

I have tried it three time and I think you can get about 4-5 extra breaths when under this thing

I will have updates and more pictures some under water but right now its winter so wait for the UPDATE

Step 1: Making Your Sam and Getting the Materials

Picture of Making Your Sam and Getting the Materials

somethings your going to need are :

-one bucket(one that can fit over your head and has enough room for a 1-2 cm gap between your face and the sheet of plastic

-one clear plastic sheet your best bet is to one have the same size as one side on your bucket(u might end up cutting it any way

-some hot melt glue sticks

-glue gun


Step 2: Cutting and Creating

the next thing you will want to do is cut out a square from your bucket using your Dremel

this is were you will put the clear plastic sheet

and the piece of the bucket you cut out can be thrown away

Step 3: Cut Your Clear Stuffz

Picture of Cut  Your Clear Stuffz

IF you have to cut your plastic to have a proper fit I left mine about 1-2mm over the actual size that way it is easier to air seel

Step 4: Putting It All Together

for this step all you need to do is glue it and drill to holes on the left and right side of the glass this is wear you will but strings to go under your arms that way it doesn't float away under water.

Step 5: The End

now that your have a bucket helmet or an idea of how to make one try it out
and remember even after you build it I will be thinking of add ons I have already started on a bicycle inner tube oxygen tank and led light head lambs for darker water or for night swimming

Try adding a air compresser to the top.

hud2000 (author)2013-08-10

This can get dangerous due to carbon dioxide poisoning. I wouldn't recommend more than two or three breaths under this thing. Has anyone even tried this out yet? I want to know how to get such a large bucket underwater.

phlox01 (author)2013-04-24

Maxmaker has the right idea. You will never get it underwater without ballast. When I made mine in 1979, we used 4 plastic milk jugs full of mud tied to rim with holes we drilled. This pretty much made it neutrally buoyant. We attached an air fitting for a hose connected to a bike pump. We had a lot of fun with ours.

Be very careful with this. If you take a deep breath and then surface with this thing, you can get what's called an arterial gas embolism in less than 4 feet of water so never hold your breath! There are several other lung over-expansion injuries you can sustain if you aren't careful but the AGE is the most serious. If you're into this thing, you can get scuba certified for inside of 300 bucks. Sometimes they have scuba expo's that will do it for 100 or even less! Even if you want to keep trying the DIY approach, it will give you a strong base of knowledge to continue your (quite fatal if you don't know what you're doing) hobby. I have several hundred dives all over the world and at least $30k invested in scuba education and equipment. Unfortunately there is a lot of science you need to know about this sport, especially if you're trying to make your own breathing equipment and what you don't know can easily kill you. I give you an A for enthusiasm though! My first attempt was when I was 6 with a garden hose taped to a crabbing buoy. I couldn't go more than a few feet down before it was impossible to breathe because of the water pressure and not having compressed air.

vampierwolf (author)2009-09-27

you should add a tube with a float on it so you can breath fresh air from the surface

bears0 (author)vampierwolf2009-10-24

 if you did that it would fill up with water unless you sealed it to your neck, even then you would be breathing the same air through the tube unless it was vary short in other words you would breathe and your breath would not even reach the end of the tube then you would breathe the same air in that you just breathed out

jonnyjohnson2007 (author)bears02010-12-07

Your lungs would be unable to expand regardless under even the pressure of a few feet of water. That is why scuba gear and surface supplied air is pressurized

Algag (author)jonnyjohnson20072012-05-30

The deeper you go the higher the pressure the air inside the container is.

anibioman (author)bears02010-07-24

he has a hole 4 breathing out

blodefood (author)2011-11-11

The only application I can see for this is if you need two or three minutes under water to check something in the bottom of your pool or in a shallow pond and one breath is not going to give you enough time.

aseaheru (author)2009-01-19

use garden hoses and a air pump, stay longer, one hose attached to airpump, other not.

aseaheru (author)aseaheru2009-01-19

picture, may need help on working...

Callum Snowden (author)aseaheru2011-07-26

Wouldn't work because the CO2 output pipe would make a pressure difference between the helmet and the water thus letting water into the helmet but you could do away with the CO2 tube and then the air would just bubble out from under the helmet

bears0 (author)aseaheru2011-02-16

oh no its going to melt my hea..... "dies a painful death"

aseaheru (author)bears02011-02-18


aceLED (author)aseaheru2009-06-14

i cant have a hole in the top off the helmet because te preasure inside the helmet is what stops the water from pushing its way into the helmet this isnt for going under water for hours but a kool little look i can grab an extra breath under water

aseaheru (author)aceLED2009-08-16

i think that the air pump would push it in....... i maid something like it, but with no pump...

aseaheru (author)aseaheru2011-02-18


Foozinator (author)aseaheru2009-03-17

Be VERY careful using normal air pumps. Most air pumps leak a little bit of their lubricating oil into the air they pump. This is NOT GOOD to breathe! Properly filtered air pumps are available and won't mess up your lungs.

NO NO NO NO NO NO! PLEASE NO! YOUR GOING TO MAKE YOUR MAMA CRY! First let me say that you are in good company, a man named Leonardo Da Vinci came up with almost the same design, but their are some proplems with your design. You are obviously very clever fellow, but..... I've been a diver since the 70's, I know what I'm talking about ok. Most pumps are lubricated with oils that produce carbon moxide at very low working temperatures. Pumps that produce human breathable gas require special materials and lubricants. CO is BAD STUFF, once it gets in your blood stream it binds with your red blood cells, this makes it hard for your blood to carry oxygen in and CO2 out. At best your going to get a world class headache, at worst, you could end up dead. Without a supply of fresh air CO2 will build up in this helmet VERY fast and you do not want a CO2 hit (trust me, I'm a closed circuit rebreather diver). If you do have a supply of fresh air (as in breathing gass rated) and you manage to get to the bottom of a pool, take a deep breath and bolt to the surface, you WILL pop your lungs like wet paper bags. Go to Wikipedia and look up hypercarbia and Barotrauma. If you want to learn how to dive, just look for a local dive shop, many of them will let you try scuba in their pool for free. SCUBA diving is a very cool sport. I love every minute of it, and over the years I have logged many hours underwater. If you do try diving, I'm sure you will love it too, but PLEASE BE CARFULL. Have fun and be safe! Angry Boomer

geekazoid (author)Angry Boomer2009-06-05

thank you. Someone who at last who knows what he's talking about and uses common sense.

aseaheru (author)geekazoid2011-03-12

hes not the only one.
look arround, and i know it, so dont rub things in. dont you make mistakes?

An Villain (author)Angry Boomer2010-06-12


aseaheru (author)Angry Boomer2009-11-12

sirgical pump.

Hey , I dive too! And I would recommend NOT TO USE THIS IBLE !!! It WILL kill you... Not only you will have an overload of CO2 in your helmet (and you die) but the amount of air will shrink as you get deeper... BE SAFE AND JOIN A SCUBA-DIVING TEAM!!! (What you could do is make it sealed on the bottom and put a valve in and connect a Snuba thingy in...) (Snuba is like Scuba diving but without bottles on your back... so you are attached to a boat)

aseaheru (author)Angry Boomer2009-04-03

roger that, but what if you have aqua lungs tubes or something on the boat? compressed air?

lilpepsikraker (author)2009-08-04

I'm not getting how in the hell you do anything with this. The bottom has a huge hole that water will RUSH into.

aseaheru (author)lilpepsikraker2011-03-12

where douse the air go?
try a cup in a bathtub.

The water wont rush in because the air is trapped inside. Run a bath and push an upside down cup straight down. The air will be inside the cup and the water wont come in with it.

11ericg (author)2010-08-15

there is a much funner and better way to breath under water its called scuba diving i got certified for about 200 bucks rent gear for 40 bucks and your set

RobertNelson72 (author)2010-08-06

With the your head in the bottom of the bucket you can breath for a minute or two. With the tubes going in and out it may not last long. If those check valves are not perfect air will by pass them and the bucket will flood. Word of warning if you use any kind of metal coupler or fitting YOU MUST make sure it is O2 cleaned. If you breath in the oil that coats those parts, you will not be happy. It can and will kill you. Cool thing to build just do it safe.

naruto the ninja13 (author)2010-07-24

hey about your title change it to Breath Under Water it looks beter and update with the peoples suggestions of making one tube with a float conecting to the surface and a one way valve and another hole in the helmet with a one way valve letting air out then find a way to seal it around your neck and make a better mabye metal helmet with a strong plexsiglass window rivited and sealed to the helmet, not just the weak plastic bucket and a thin plastic sheet hot glued on to be honest you can suffocate your self by breathing in you own carbon dioxide and your window would probably break at more than 6 feet deep

allen (author)2010-07-23

Google "hookah rig". If you don't have an external source of oxygen, or better yet air, you'll get about half a dozen breaths out of your bucket before CO2 buildup becomes a problem. Keep in mind that you're under water and you don't know what you're doing. I don't mean to be harsh but you're going into an inherently dangerous environment without a clue about the dangers. That's not a prescription for a good outcome. You don't need to learn a lot to be adequately safe hookah diving, the rigs are popular in resorts where completely ignorant tourists use them after a half hour of instruction, but there are things that can go wrong and if you don't have a clue those problems can kill really, really dead. If you're building your own hookah rig you've got to add learning about the problems associated with *that* to avoid them. Hookah rigs are simple and fairly cheap but that doesn't mean they can't be screwed up. You know what happens then.

lamboboy732 (author)2010-03-13

I didnt read all the coments to see if someone saig this already but to hold that buchet even 3 feet under water tou are going to need over 100 pounds of weight. Not to mention the plastic covering which will implode at about 5 feet or more under due to the weakness of hot glus vs. water pressure. By the way i have dont this before so i know the risks and toughness of pulling it off safely.

lamboboy732 (author)lamboboy7322010-03-13

Sorry forgot to check spelling.

kingbob9_9_ (author)2010-02-28

you shoud add tubes so you can stay under longer.and attach some thing that can float so it dosnt go under.

aseaheru (author)2009-11-12

the new way things work
it is good.

bears0 (author)2009-10-24

 in this apparatus I am using two one-way valves, a gas mask, and a tube.
do you think it will work?
if so which one way valve's should I use to prevent leaking and where should I get them.

thank you

Andrew Cline

d2j5 (author)2009-10-16

just dont do this. if you want to swim under water get scuba certified. alot easyer and safer than useing a bucket. i like your idea though and you could just make a giant snorkel go underwater with just a facemask and do it that way than put a bucket on your head.

im getting certified and its really not that hard at all, costly but defintly worth it because you do it once and thats it! unless you need a refresher corse basic review blah blah blah.

maxmaker (author)2009-07-27

I made one and I noticed it was quiet hard to bring the whole thing under water so I attached two large cannon ball fishing weights to the side and it word to give me a more free feeling in the water I also made a light module using a plastic bottle and some led lights to make a sort of a under water lantern I also put weights in it as well

iProton (author)maxmaker2009-08-19

I think that a heavy air tank would work :D

sharlston (author)2009-04-07

drill a hole in the top and put a garden hose in it and seal it with silicone and keep the other end obove the water and breath through your mouth

cafriend (author)sharlston2009-05-26

Anything much longer than a snorkel and you'll start breathing the air you just exhaled.

aseaheru (author)cafriend2009-08-16

see above

cafriend (author)aseaheru2009-08-16

See the dates.

sharlston (author)cafriend2009-05-26

ye unless u wait a couple of seconds for the air to escape

aseaheru (author)sharlston2009-08-16

but have another one to push the air out...

aseaheru (author)aseaheru2009-08-16

note, have valves

When i saw this something popped into my head, BELL SUBMARINE!!!
