I have 2 old empty CO2 fire extinguishers for scrap.
They're just over 4.5" dia x 16" o/a height. The original capacity is2kg CO2.
They may make good exhaust pots or could be cut up to make wheel rims or wind chimes. The possibilities are endless.
I need the space more than the potential but thought I would offer them to you guys before taking them to the scrap skip.
