A spectacular illusion!
The two chemicals in AB Blood combine to produce a dark red liquid that looks just like blood.
Simply apply solution A to one surface (like the skin) and solution B to another surface (like the backside of a knife). When the two surfaces come into contact, they will produce realistic fake blood.
AB stage blood lets you recreate and film the appearance of a cut or wound as it is being made.
