Steamshy, Whaaaat? cant think of a use for them?

Try this, it will give u great enjoyment! (or a headache!)

Step 1: Buy a soda syphon

step 2: use cartridges to make soda water, chill in fridge.

step3: make ice cubes

step 4: mix the ice and soda with your favourite whisky, at a suitable ratio of course!

step 4: at drink O'clock, consume at your leisure!

Then again you probably already did that, and these ones are empty!

Oh well, in that case I'm like you, cant think of a use for them!!

If they are "sparklets" bulbs I used to use them at school to make small self propelled projectiles. I'm sure the health and safety brigade would not approve but a length of tube (samish bore as the bulb) with a firing pin (from a flare I dismantled that my dad had brought back from WW2 and hidden in the loft) made quite a good rocket system! You had to carefully file down the lead end first to make it thin enough so the firing pin would make a good hole and if you took too much off it was a bit of a disaster.

I DO NOT RECOMMEND THIS IRRRESPONSIBLE SORT OF ACTIVITY! It was in a slightly different era when teachers encouraged an enquiring mind……………………. I won't go into other "rocket" experiments which I gave up after one of them blew up on the launching pad – and I discovered a one inch "Jetex" fuse was not quite long enough!

You could send one to Mike Suffolk, he'll need it for the Matador "silencer".

Rod

Tsk! Tsk!

If the kids of today did what we did in our schooldays – they'd end up in Guantanamo Bay wearing zip-ties for bracelets.

My air rifle takes CO2 cartridges that appear to be a slightly different size to sparklets bulbs.

Neil

Are the cartridges similar to these by any chance?

If selling on eBay beware of their prohibited items categories, otherwise you could end up with the listing being pulled and a policy violation recorded, I got done recently for a similar misdemeanour!!
Also check the courier's prohibited items, because any pressurised container with the potential to explode in an aircraft is likely to be banned!
Although some carriers will take them, I haven't found one with sane carriage costs!

I've got a couple of similar unused Butane cart's here, they're like rocking horse crap to find, but I can't sell them because I can't post them!

but contained Co2, Postage would be a problem I guess so have ruled it out

My air rifle Co2 bulbs were supplied mail order from an Ebay vendor – 50 off sent in a Jiffy bag via Royal Mail. Also had a 2kg Co2 fire extinguisher supplied mail order via courier.

There appear to be several sizes for these – I use the plain neck "Crosman" type in the air rifle (14g Co2 IIRC), but used a smaller plain neck type (8g IIRC) for pressurising barrels when I used to home brew (they also fit the "charger" for a Humbrol C02 model aircraft motor). The tyre inflation bulbs in the motorcycle repair kit are bigger than either of the previous two & have a threaded neck for the tyre adapter to screw on to.

Could machine a small cylindrical holder for them with a point to burst them as you screw the top on and a small valve to let the CO2 out as required – a handy source of small amounts of compressed gas when a compressor isn't nearby. Could also be used to power a steam engine for short periods of time for quick, highly portable demonstrations.

Handy as a cryogenic agent but in these tiny quantities may not be much use for anything.

I think they're planning to ban breathing soon because of the potential health risks…

I assume they are pretty strong so how about minirollers for moving machines.

Meanwhile I keep wondering about a use for plastic milk bottle tops. (Bottle part cut off is a handy container)

I would guess the cylinders are made of aluminium

All the small cylinders I have used are steel. See how Crosman make theirs here :

Neil, I just have one of the Chinese Crosman rifle clones – a QB78. The fire extinguisher is intended to be a bulk refill station, when I get all the parts together.

The casing of these little cylinders is (at a guese is somewhere about .025"/.0390", have not actually measured one. Saw one use in a shop in town that sells some doubtful items, about 10 mm of the base of one brazed on the side of a second one, and a hole communicating between the two parts, looks like a little smokers pipe, yep, a bong, and all nicely chromed.

  Used one as a pressure vessel on a little water pump.  Also used a CO2, and a slightly larger niros oxide one to make an oxy ascetylene(?spelling) set for a model workshop.   Ian S C

spent bulbs make decent handles for files
