How to build a deathtrap

1. Select the location. Your deathtrap must blend in with the environment until the time to use it arrives.
2. Decide upon the animals. Will it have a pit of snakes or a tank of sharks?
3. Fine tune the sequence of events. This trap will begin with an iron ball rolling down a pipe and knocking a stapler off the table. The stapler will land in a bucket set on a balance scale, which will add enough weigh so that a burning candle is lifted toward a rope. The flame burns the rope, which causes a boulder to fall exactly where our hero will be immobilized.
4. Choose the style of trap. Spiked walls that move steadily closer or a room that fills with sand? Whichever you choose has its own set of tools required to make it work properly.
5. Know how many heroes the trap will need to accommodate. If the trap is too small, then it may miss some heroes. While if it is too large, a single hero may be able to slip past without setting it off.
6. Bait the trap. Is you hero insatiably curious? Then disguise the trap's trigger as something the hero will be drawn to. A big red button works quite well.
7. Have the trap contain the hero's weakness. If there something that can cripple the hero? Whether it is ornithophobia, the color yellow, or a green meteorite, make sure it has a place in your trap!
8. Build a fail-safe trap. If the hero somehow defeats the first trap, then a secondary trap may prove successful. Who would would expect there to be a trap within another?
9. Prepare a speech. Taunting the hero is one of the great joys of a deathtrap. Go ahead and give a speech worthy of the hero's demise.
10. Leave a flaw that the hero can exploit to escape. You don't want to have to find a new hero after all.
