There are two rooms.
You are clad in only your undergarments, and these are sodden in corrosive acid, eating away at your delicates. You are timed. If this acid eats away your delicates, it will enter your blood, eating away at you. Don't let that happen. Oh, and for the smart ones, no, you can not remove them. They are well secured onto you with a chemical that can only be removed with another chemical, which you can not obtain and do not have, and you dont know what chemical has secured it on and what chemical you need to get rid of it.
You have nothing else with you, and if you touch your undergarments to try and tear them where the chemical has not secured it, or tear it with your teeth, the acid will attack your teeth/hands anyway, so you are still timed.
You are in a room consisting of a floor and walls filled with alarms. And a massive, extremely strong fan. And a ceiling with sprinklers distributed around it.
There is a locked door with no handle nor keyhole at the end of the room opposite you. It is opened with a button.
This button happens to be on the floor, desguised as one of the many alarms that are on the floor also. Your job? Try to press the right button that opens the door. Press a wrong button? The sprinklers are activated with the same corrosive acid that will eat away at you in minutes. Try to escape, and run to a hospital and get help, without being eaten away.
Oh, and do not forget the fan. It will be blowing away so fast and strong it would literally blow you off of your feet at any wrong move. You do not want to be thrown against the opposite wall. For these alarms release hundreds of killer bees from the deadly rainforest. The bees come from a hole adjacent to one certain alarm. These bees are angry, mind you. Ten stings could kill you. And remember, you are clad in only undergarments that are eating away at you.
P.S: Try to escape through the bee hole, and you will face a dead end with a big machinery wall separating you and the bees. Once it senses you are in the bee hole, it seals off the backway into the room and opens the door, so you are trapped with the killer bees with no escape.
