My 4 year old asked me and I think it’s a rather good question that I would like to answer so she understands. Thanks 🙏🏻

Water is see-through because it lets light pass through it easily without changing the light’s direction too much. Light is made up of tiny particles called photons. When these photons travel through air, they can easily pass through because air is very thin. Water is thicker than air, but it is still not thick enough to stop most of the photons.
When light goes through something, like water, we call it transparent. Water is transparent because its molecules are arranged in a way that doesn’t block or scatter light much. This means we can see through water because the light can easily pass through it and reach our eyes, so we can see what’s on the other side.
