This trap was made to demonstrate the usefulness of silt, a great addition in 1.1. What you will need: A) 2 active stone blocks B) 1-2 stacks of silt C) torches you don't mind losing D) 1 pressure plate (grey) optional - bucket The picture above shows the trap when set. You should probably have the torches lower down to hide them from sight and create a deeper pit that is harder (impossible?) to get out of. Here is the wiring diagram. And finally the trap when set off Some tips- You might want to have the pressure plate in a one-block deep pit in a dark passage for less visibility. Also, I could have put active stone blocks above the pit to hold back more lava above. Thanks to Limeth for the idea of using torches to hold up sand (see post 'traps that kill people') in this section.
