So here's what your gonna be needing to ruin someones day, and their clothes, and put a dent in their pride! >:D
a bucket of water
and a victim (one who is a slow runner, if you know what I'm sayin)
Step 2: Set up
so, simply what your gonna do is have the door be open enough to prop he bucket on. then hop on your ladder and place the bucket, And the trap is set!
Step 3: The big finale
So, once the trap is set and you know your victims name, Call it really loud, maybe make it sound like somethings wrong, then step back, and get ready to run! cause when he/she sees you laughing your gonna be in a world of hurt unless you run. ENJOY!
