“This homemade LEGO flamethrower is completely built with LEGO toy building bricks. Only thing not LEGO is a piece of string and a refill bottle of butane gas which is commonly used in butane lighters and can be bought in almost any supermarket or grocery store.”
It works by “winding a little round knob which pulls the string which pulls the lever which pushes the bottle of butane against a holder with a hole from which butane shoots out from”.
Sounds really cool doesn’t it? How about a video of it in action? Check it out below.
