Rachel sits and ties her ankles apart and to the floor with more ropes around her knees and tied to metal rings on the wall behind her with springs in-between to keep her legs under tension and apart. Next Rachel makes sure the key to the padlocks are in reach behind her then positions a small set of weighing scales in front of her with wires coming from them to a small winch above her. Next Rachel gags herself and secures her wrists into leather cuffs and padlocks them to a chain behind her then pulls a rope to raise her arms. Very quickly Rachel starts to dribble which is collected into a container on the scales - All she has to do is keep filling the container with her drool until the weight is enough to operate the electrical contacts and switch on the winch to lower her arms so she can reach the key to her handcuffs and release herself.
