Hydrogen Tank

Hydrogen is the reason airships went out of fashion. Stored under pressure and desperate to escape, this gas spreads fire like piss in a paddling pool. It gets everywhere fast, turning small flames into sprawling chaos before you can say "Rauchen ist hier nicht erlaubt, mein Herr." When used properly, Hydrogen leaves barely a trace of its existence behind in the aftermath. So long as you remember to pick up the big-ass metal tank when you're done. As Torn's mascot Trashie the Trashcan says, "Littering is Shittering!"
