Its not Liquid Nitrogen

Picture of Its not Liquid Nitrogen
Ever wanted to freeze balloons so they shrivel up?
But you couldn't get your hands on industrial quality liquid nitrogen?
(if you can allready, then there is no need to look at this)
Well now you can! sort of.
the stuff were using is not liquid nitrogen, but something that is commercially avalible:
COMPRESSED GAS DUSTER! YEAH!

Step 1: Other stuff you'll need

you'll need...
1 compressed gas duster(as mentioned)
1 thin walled balloon(like a water balloon)
1 means of holding the balloon(hands might work but they might freeze)
WARNING:THE GAS IN THE COMMPRESSED GAS DUSTER IS FLAMMIBLE!
IT IS YOUR OWN RESPONSIBILITY IF YOU WANT TO USE IT AS A FLAMETHROWER(whoops)
WARNING(again):THIS STUFF CANOT ONLY CATCH ON FIRE, IT IS REALY COLD I WILL NOT TAKE ANY RESPONSIBILITY FOR FROSTBITTEN OR BARBEQUED FINGERS; ATTEMPT AT YOUR OWN RISK. MAXIMUM VENTILATION RECCOMMENDED, OUTSIDE IS THE BEST WELL AWAY FROM ANY SOURCES OF FLAME!

Step 2: Inflation: its a good thing (at least in this case)

Fill the Balloon with the gas, NOT AIR!
I REPEAT NOT AIR!
(it just wont work you can try if you want)
then tie off the balloon and hold on to it by using "your means of holding the balloon"

Step 3: Freeze!

Picture of Freeze!
FILE0197 copy.jpg
Turn the COMRESSED GAS DUSTER UPSIDE DOWN
and pull the trigger thing thus releasing the negative 100degree centigrade liquid gas(oxymoron?)
onto the balloon making it shrivel up before your eyes!
WARNING(again, again, again):THE GAS IN THE COMMPRESSED GAS DUSTER IS FLAMMIBLE!
IT IS YOUR OWN RESPONSIBILITY IF YOU WANT TO USE IT AS A FLAMETHROWER(whoops)
WARNING(again,again,again, again):THIS STUFF CANOT ONLY CATCH ON FIRE, IT IS REALY COLD I WILL NOT TAKE ANY RESPONSIBILITY FOR FROSTBITTEN OR BARBEQUED FINGERS; ATTEMPT AT YOUR OWN RISK. MAXIMUM VENTILATION RECCOMMENDED, OUTSIDE IS THE BEST WELL AWAY FROM ANY SOURCES OF FLAME!

Step 4: You did it!

But how does it work?
the gas is in a liquid form as it exits the can,
but as it contacts the balloon, the liquid evaporates
the resulting rapid evaporation of liquid gas(oxymoron again)
takes some of the balloons heat with it (stealer!)
making the balloon shrivel up!
NOW YOU KNOW!!!

This is a great Instructable, but you need to add a main image of the final project to the intro step. Please do that and leave me a message when you have so that we can publish your work. Thanks!

And the gas inside turns into the same liquid you found before.


Heres a cool trick idea!

Shrivel it up and cradle it between your hands and watch it inflate back.

Good trick if you have young nephews or nieces.
Interesting! I had no idea Dust off would do that to a balloon. I am just not sure what the use for the "frozen" balloons would be. Is there a point? A use for "frozen" balloons?

I have yet to find practical applications for baloons filled with a low boiling point liquid. Freeze spray is Dust off only it is designed to spray the liquid gas. (Notice the contradiction.)

Neat idea!
And some of the comments have especially interesting tips!

Would someone go into more detail about what shriveled balloons are used for please? I'm lacking some context to wrap around this experiment. It looks like there's something to this, that everybody else knows, and I don't.

Humor Alert: (Mark this day on your calendars, tell my family I just admitted I don't know something!)
 The "turn can upside down to freeze things" technique looks familiar. Oh yeah, I saw this in "Burn Notice". Michael turned the can upside down, and he sprayed the stuff on a lock. That freezes the lock making it brittle; he then hammered the thing. (oops, I just gave it away) If you ever do this, then I warn you that shards of the lock may fly towards you. <insert the usual disclaimer here>
I can't believe it's not Butter!... I mean liquid nitrogen!
Dont do the flamthrower under a fire alarm

will any duster work?
digitech (author)  hackthetack4 years ago
if it says "commpressed gas duster" on it, its probably it office max, the "original" gas duster, whatever works fine!
