Next time your kid locks him/herself in the aeroplane bathroom, or you just feel like being particularly creepy with a stranger, here's how you can easily unlock an aeroplane lavatory with nothing but your finger.
- Step 1: Approach locked lavatory
- Step 2: Lift "LAVATORY" sign
- Step 3: Slide the knob into the unlocked position
- Step 4: Cackle because you've just unlocked the bathroom from the outside
That's all there is to it. Kind of unsettling, right?
