Beta 1.6 Simple Trap Door Lava Trap

I’ve had 1.6 for all of ten minutes, but already a mildly fiendish plan for a very real ‘trap’door has emerged. To manufacture this trap all you need is a trapdoor (created by six wooden planks placed horizontally along the bottom of the 3 x 3 crafting grid), a solid block for the trapdoor to sit next to and a pit of lava. Oh, and a pressure plate. The trap mechanism is simple, herpty derpty enemy or mob comes by, steps on pressure plate and suddenly the floor is lava!
