A week ago we featured LEGO Ice Trays and the Top 5 LEGO Kits for Christmas. Well... The LEGO Flame Thrower one LEGO build that you won't find in the official handbook. It's also the one build you won't want your kid to make. The inventor revealed, "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."
