I have mixed feelings on this. First, it's fossil fuel, which we really need to get beyond. But, how many times have you been rescued by the side of the road with one of these? This is also exactly like the gas can I used as a kid to fuel up the lawnmower I hated using. But then again it's also the one we would "borrow" when we needed to set something on fire for a super-8 movie (kids, don't set stuff on fire, it's dumb like I was). And lastly this one's built with LEGO by Pepa Quin, so overall it has to be a positive.
