This new fire extinguisher is 20X better then my old extinguisher so that either = 20X more fire safety or 20X more trust on my rocket pants. I'v wanted a pair of rocket pants since I was a kid but back then it didn't seem possible because there wern' light weight materials like plastic and nylon so I would of had to use wood and stone to build my rocket pants and I would of needed a thruster the size of a VW. Plus back then I didn't get an allowance so funding the rocket pants would of been a nightmare. But now I jave the technology and a bit of money in the loonie jar (I save all my loonies (1 dollar coins) in a jar Cheers!
It is not a good idea to waste fire extinguishers, you never know when you might need them. Save it for its proper use.
Buy a second one and use it for the rocket pants. ^_^
The latter, duh.
Though I suppose it wouldn't hurt to follow JustAsking's suggestion and buy a second one in case of fire related emergencies.
