Story time: My parents bought an anti motion sickness thing. It was a rubber band with metal core hanging from the car’s chassis to the ground. It worked for my brother! But at some point I asked my parents: but how can this work then!? What does it do with “motion “? My parents told me to be silent and later, when my brother couldn’t hear, told me it was just to release static electricity but they told my brother it was against motion sickness and him believing that made it work for him. At the time this was pretty shocking to me.
