which fire extinguisher?

What's the best one...the closest one! Really, an ABC extinguisher is mandatory in a garage. You can get a 10 pounder for under $50.

Or hang this in your garage..the Fireball! Detonates 3 seconds after it comes into contact with fire.....How fun would it be to drop in the bonfire at midnight? Poof!!!

That's cool. Never saw those. Reminds me of the old fire grenades.
