What can I make out of 200 spent NO2 canisters?

Raza do you work somewhere with a lunch room? That’s a great place to put free food stuff that you want to disappear.

My thought about the used ones…please remember that while I looked them up online, I have never held one. So here’s my artsy-crafty idea: make a wind chime out of them. You can put different amounts of water or oil in them, then rig a bent wire inside to make a hanging hook and string them up onto a bent coat hanger hanger.

You can make a wall mural spelling out “I survived 90s rave culture, so no virus named after a weak beer is gonna kill me”

So the usable cylindrical length is maybe 1.5-2 inches. That should work as the bridge on an electric cigar-box or other bass 'ukulele. I wonder if filled and empty cylinders would produce different tones?

We would pack potassium permanganate in a little Testor’s paint jar, ram a wad of cotton on top, squirt in a bit of picric acid, then quickly screw the cap on and flush the jar down a school toilet. Then await the fecal explosion in a classroom downstream. Don’t try this at home, kids. Or at school or the office. Wouldn’t be prudent.

Back when sailors were iron, ships were wood, Christ was a seaman apprentice, and I was doing coffee houses the vials the pharmacist gave you your Rx in were made of brown tinted glass. Which you could slide over your left ring finger and apply to your guitar strings. I guess if you cut off the pointy end of a whippet bottle and applied some serious polishing you could use one as a slide.

Not legal ones.

It sounds like you coulda put an eye out! :eek:

But seriously: a spent CO2 cartridge filled with blackpowder and ignited? That’s not too far removed from a hand grenade, is it? Those fragments are carotid artery-seeking missiles. That wasn’t wacky teenage skullduggery, that was a special kind of stupidly dangerously stupid danger.

You worked and trained so hard for years in pursuit of the Darwin Award only to lose out in the end to freakishly bad luck—the odds must have been astronomical that you’d survive to adulthood.

True, but you really don’t have to cut them. Imagine that you have a cardboard box that you were going to have to recycle anyway. Tip it to a 45 degree angle with one corner downward and stack the items inside until you are at the area (square inches?) that you are looking for. Next, punch a hole through the sides of the tipped box that is about halfway from the floor of the box to the height of the cartridges on each side. Feed string through the holes and create tension on the cartridges as tight as you possibly can (the string should hold the cartridges in the stacked position tightly. Next, while keeping ‘as tight as you can’ tension on the string, carefully cut the box with a box-cutter… from the first punched hole around to the second punched hole.
You are then going to pull the string through the cut…then tie off the string tightly once that is done.

If it’s done right (and it should work) you’ll have a circular grouping of the cartridges which you can glue/solder together. Once dry, cut off the string and you’ll have your trivet. I’d recommend using it ‘round sides up’, but it all depends on how you’re going to use it.

There’s a few examples of art you could make. Someone made garden art flowers. This guy is making sunflowers. This guy is making garden tiles/stones with them.

I thought I’d find more cool stuff on Etsy but I didn’t find anything made from the canisters. My thought was to put a hole through the top and put it on a ball chain or a keychain. This one person on Etsy made a custom belt that looks kinda cool.

A brooch? A pterydactyl?

I wonder if they can be made into tiny ocarinas…

They’re just 7/10 inch diameter so that should work. Unless accidents happen. I had one of those dark glass pill bottles that fit my left pinky JUST right for sliding on my Kay dreadnought tuned open D. Then, at a swimming hole in Rhode Island, I slid down the rope… and broke my pinky on the knot at rope’s end. That bottle, and a piece of brass pipe JUST the right size, no longer fit. My slide attack was ruined. It’s been all downhill since that day in 1969. :smack:

You’re going to mass-produce the fipples?

Bells. I think these can be made into bells.

Either by cutting off the rounded end and flaring it, or by cutting slots and curving the cut flanges inward in the manner of a sheep bell

CO[sub]2[/sub] cartridges are the same size. I never has 200 of them, but only a few at a time. I’d use a syringe to fill them about ½ to ⅔ full of water, and then stick a toothpick in the hole. Using kitchen tongs, I’d hold the cartridge over a flame. (It could have been a can of Sterno, or it may have been a blowtorch. My memory is hazy.) When steam was trying to escape past the toothpick, I’d pull the toothpick with tweezers and let go with the tongs. The cartridge would jet off down the street.

Making 200 steam rockets isn’t practical, but they’re amusing as a pre-teen.

I really like those flowers! The description did say that the cartridges aren’t “very nice” to weld, though.

They are zinc plated, so there are risks (metal fume fever) involved with getting them hot

So - morris dancing?

:smiley:
