The Plastic Tank is an action-packed, "Safe & Sane" novelty ground firework that drives across the pavement while emitting bright titanium sparks and loud whistles. This retail 2-pack features a green tank with green sparks and a black tank with red sparks, both finishing with a fun, crackling "snake" effect. Best of all, the durable plastic vehicle shells remain completely intact after firing, leaving you with two bonus toys to play with later.
