Instructables
This is a rather involved instructable; however, the reward is well worth spending the hours (and i can guarantee you will spend less time on it than i did -- i had MANY problems which i will explain how to bypass). I like dualism and this project is perfect for me because the final product serves as both a normal can of Dust Off and a place to store some small valuable items.


The first step is to obtain an empty can of dust off (or another empty can of compressed air). Obviously if a can is empty you may not have one laying around, so i CAREFULLY emptied an existing can which was low on gas. Follow the set of "DO NOT's" on the back and carefully use spray it until there is nothing left. Now comes the fun part.

Step 1: Gather Materials

Pictured are the basic materials which you will need to create the Working Can Safe. This picture was taken before i started the project; i later learned that the Gorilla Glue will not work, so do not use the Gorilla Glus in the later steps. In searching for a bottle, i found that a "Move Free" vitamin bottle is a perfect fit. Whichever bottle you decide to use, make sure that it fits (step #3) and that the cap is a normal screw off, NOT A CHILD SAFETY ONE!.

I did this with a deodorant can. I got one of those little straws that come with WD40 and connected the modified can to a normal can and just pushed down the nozzles of both with my finger. Seems to work well.

Some grocery store carry dry ice. you need to call the store to find out which ones carry dry ice it In San Antonio theres HEB,but all the stores don't carry it. So call. Also you an get dry ice at an ice processor plant. Most cities have a plant that makes ice for grocery stores and restaurants. You need to call around to find the nearest one to your location.
Heck, even Wal-Mart and our local grocery store chains all sell dry ice.
I got a sizable chunk with an order from Omaha Steaks, but they say that it should have all sublimated before the package is delivered.
I know this is old... the publix by my house sells dry ice.
Quality Dairy main distributing center in Michigan has it for sale. look in the yellow pages though for your area
anywhere that sells compressed gas and other gaseous chemicals. i go to Praxair when i need dry ice for "projects".

genaurdi's...in my area genaurdi's is a branch of safeway. they sell it for $1.99/lb, so its really cheap and readily available.

i saw a store that sells commercial ones and the labels are from real products
i thought this meant that you drill a hole in the safe and you fill it with the liquid thats inside.
Then freeze it, with ice instead :/
And you would get a Safe Cube! :)
sounds delicious
no just the door so you cover the mechinisim

i'm like 99% sure this is not considered cracking a safe, but making one.
me too. It is makin and breakin a safe. Money down the drain,whoooooooooooosh....
j626no (author)  nafango226 years ago
or a play on words during a competition to draw attention....
murrga bu!
I clicked on the instructable thinking it was to teach you how to crack a safe with dust off, lol.
anyone here
it's not a chatroom

what do you mean is anyone here?....no, the can made itselt?lol

Down South they sell dry ice at grocery stores. In the North, check the Yellow Pages for Ice Cream distributors, like where the Good Humor guy goes to get his product every day.

lets say i had another can of dust off, could i conect the full can on one end of the straw, and the safe can on the other and depress both triggers until the pressure equalizes?
j626no (author)  fireman joe7 years ago
that would work; however, the liquid inside the normal can is what expands causing the gas to escape (thus it gets colder) and therefore when they equalize it would be very low pressure (equivalent to how much pressure is applied by the trigger as this keeps all the pressure in). now if you wanted to completely disregard safety, and hypotheticaly (wink wink) turn the normal can upside down so that it sprayed the liquid into the other one, now that might just work. one would just need to be careful that the liquid didn't touch their skin or frostbite would occur (as well as cell death). but ofcourse this is only a hypothetical suggestion. if one ever tried this, i would like to know how it works out. thanks and good luck
that is fun to spray on a table and then push into a pile and than tap... or spray it on your laptop screen... it is so cool... it seems to freeze...

"Instant Cell Death" upon touching dry ice or liquid propellant is really a load of rubbish. I have spilt liquid butane and many other propellants on my hands and it is cold, however it DOES NOT CAUSE INSTANT CELL DEATH as my hands are both still perfectly fine. The liquid evaporates very rapidly, but your skin has a layer of already dead cells on top that insulate the live ones. I have also handled dry ice; this can cause frostbite but is also possible to handle safely, but for no longer than about 2 seconds, and keep it moving.' Please do take every precaution, but don't be stupid or you will get frostbite.

Thats awesome! did you come across any problems or did i help you avoid them? also, how well does it work? Thanks for posting a pictrue, you did a good job! jon
well i didnt have any problems only i didnt have ny jb weld and couldnt get gorill glue to work so i used hot glue. ill probably pull it out and reglue wen i get some JB weld or some epoxy so itll hold air but for now it just is an empty can with a compartment in it

Once the bottle is in place..centered & to the correct depth.. turn the can bottom up minus the lids and put a stout bead of epoxy around the neck of the bottle to the base of the threads.. This should seal the bottle to the sides of the can with an air tight & pressure resistant seal. Just keep it below the thread line. You might want to rough up both surfaces with sandpaper for a better bond. What thinks ye.?.?.? FN
j626no (author)  FN647 years ago
sounds good. i did rough it up, you'll notice in one of my steps a pink sanding foam piece (something cheap from Home Depot). And i used wood glue because i made my mistake with Gorilla Glue. See, i thought gorilla glue was like an epoxy...i was sadly mistaken :-( but yeah, thanks for the advice

oh no! not instant cell death in skin! aaaahhh!.....
I'd like to point out that Pampered Chef now sells a can opener that lifts the lid off the can by prying the side rather than cutting. Do you think that would work on these cans?
j626no (author)  Erik Lindemann7 years ago
it should...i was actually going to use that style as i have one at my work; however, i forgot and had to make do with my girlfriends. it worked fine only i had to go real slow and sideways....also, you cant use too much pressure or the gear is going to leave little dents around the bottom of the cap, so yeah, give the pampered chef one a try

i bet the dry ice would work better with the JB weld...though...it might push the JB down and glue teh cap shut...hmm...worth a shot hehehe next would be to work out a way of refilling the thing..as keeping your stuff in...what is basically trash is a bad idea (#1 because mothers tend to throw trash away #2 "why do you have an empty can of...OOOOHHHH the bottom twists off..SCORE!!") maybe you could attach some form of fill tube with a one way valve through the bottom of the bottle on the inside....that way when the preasure is gone you could refill with a compressor...or more canned air etc... nicely done indeed!
j626no (author)  crapflinger7 years ago
it is refillable...you dont need any of that, just depress the trigger and refill with compressed air and release the trigger. there will be a quick shot of air inside of the can...i do like shark's idea of equalizing them though..i had thought of that, only i just used the last of my compressed air. :-)...thanks for all the ideas though
yo ucould have linked the straw from your can to a full can of compressed air (or spray paint) and sprayed. it would have filled it up untill it equalized the preasure.

i might do an instructable on the matter =)
