My grandfather is a master of water ink painting.

Heavy water is used as a coolant in nuclear reactors.

Every morning, I swim in the pool.

He is bad at remembering numbers.

Seawater contains salt.

I use warm water to make coffee.

My father underwent pancreas surgery.

He always expresses his feelings honestly.

At the church, he took the holy water in his hand and offered a prayer.

He solved the problem using lateral thinking.
