Lock them in small room with only one exit...
a small hole .. but big enough for him to crawl into
then give him a time limit to escape
The walls start closing in so he has no choice to quickly get into the hole or else it will get covered by the walls and then the only way out would be to go up to heaven muhahaha
Anyways 90% probability that he will crawl into the hole
but what he wasn't told was that the hole had sticky goo in it with glass shards stuck in it all the way
The Person has to keep crawling all the way through the hole cause once the floors/walls above him close ... his air supply is shortened
He has to quickly go through the goo and glass , cutting himself while not to overexert himself as to quickly deplete his oxygen supply and die on the way
Anyways 75% Probability that he manages to come out of the hole to another room
This room has would be a dead end instead of one door
95% probability that he will run towards the door and open it
99.99% chance that the door is rigged to a spark creating mechanism :hanabi:
which will ignite the odorless and colorless highly flammable gas in the room
toasting the victim . :atsui:
the victim may R.I.P :imd:
