Bob started with all of his friends in the ocean after they were all parts of the collection process.
One day Bob felt something weird. He started to fly up into the sky. This happened because it was very cold and Bob forgot to put on his jacket. The molecules inside of Bob all escaped so he started to evaporate.
When Bob got all the way up into the sky, condensation started to occur. This happened because his water vapor molecules became liquid water. Bob was ecstatic that he turned into a cloud with all of his friends and he even threw a 1-day reunion. He even learned about cloud formation.
Bob landed on a mountain and he had a lot of energy so he ran off the mountain surface which was surface runoff. He was going so fast that he ran into a forest. Bob then got sucked up into the plant's roots.
After a few days in the plants roots, Bob flew up into the sky in the form of transpiration. He evaporated into the sky again because the molecules inside him escaped. Bob then turned into a could again through condensation.
When Bob was back with his friends in the clouds, he wanted to invite more. As more and more of his friends came over, the cloud got heavier and it finally rained again. Bob landed straight onto the soil on a farm. He sunk into the ground and was stored as ground water.
