How do pasties stay on?
In: 1
Van Der Waals force keeps the adhesive stuck to your skin, like a bandage.
When enough sweat accumulates (if the pasty or bandage can’t breathe) then the Van Der Waals force is overcome and it can slide off. But usually this is taken into account. Also, most instances of the use of pasties or adhesive bras are cool enough that the person isn’t sweating that much.
