That “bent” spoon isn’t broken. Your eyes are being fooled by light!
When a spoon is placed in water, it appears bent at the surface. But the spoon itself hasn’t changed shape.
Outside the water, the spoon looks perfectly straight. This proves nothing is wrong with the spoon itself.
The strange appearance happens only when part of the spoon is inside water and part is in air.
When light passes from air into water, it bends because water has a different optical density.
Refraction makes objects under water appear shifted from their real position.
Your eyes follow the bent light rays, so the spoon only appears bent. The spoon remains straight.
