Here is a hero EDTA dart from Stephen Norrington's action horror BLADE.
Blade (Wesley Snipes) used his EDTA darts while attacking Deacon Frost's (Stephen Dorff) hideout.
Their anticoagulant acid exploded on contact with vampire blood, and Blade injected Frost with multiple doses during the climactic battle, causing the vampire to explode.
The dart consists of a brushed faux-silver aluminium canister containing a green liquid within a glass tube.
The liquid, which is blue in the film, has become discoloured with age, and the canister displays minor scuffs and scratches from production use.
