Neck cuff escape
A neck cuff is hard to unlock, because you can NOT see the keyhole! You have to feel your way around, it takes a lot of experience. I will make it even harder this time! I neck cuff myself to the radiator, and then I handcuff my hands behind my back, wrists stacked. I can reach the key to the neck cuff, but the key to the handcuffs is out of reach. This means I will have to unlock my neck cuff with my hands cuffed behind my back! Will I escape?
