In a world where pressure only affects objects when they are observed, what will happen to Sayuri as she dives into an unobserved pool wearing a delicate dress, followed by her friend Kofi who stays at the pool's edge watching her dive?

Provide a brief response.
As Sayuri dives into the unobserved pool, her dress will not experience any pressure since no one is observing it; thus, it will remain undamaged despite her diving into the water. Once she is underwater, unless she observes the dress herself, it will continue to experience no pressure. However, since Kofi is watching her dive, the moment Sayuri breaks the surface of the water, the pressure will then start to affect her body as she is being observed by Kofi. This means she will feel the resistance of the water against her skin as she would in a normal dive, but her dress will only begin to feel that pressure when it is observed either by her under the water or if Kofi's line of sight allows him to see the dress under the water. If he only sees Sayuri and not the dress when she dives, then only Sayuri's body will feel the pressure, while the dress remains unaffected until observed.
