Creative Kill Chamber 2.0

You finally reach the science lab that you were trapped in your entire life. Just a year ago, you had barely escaped the horrific room of death in the lab and now, free from the clutches of the evil scientist, you decide to take revenge. You had kidnapped the evil scientist as you escaped and decided to bring him to his demise in the death chamber. You lock him in the room and enter the control room. There are a numerous amount of buttons on the control panel and each is labeled with a lethal object. It's time to get CREATIVE!
