How did the moon affect the water in Armstrong's body?

Question

On earth, the tides are in part determined by the Moon. So what happens when a body full of water attempts to walk on the moon?

Answer 1

Tidal forces affect all matter, not just water.
They are caused by the DIFFERENCE in gravitational attraction between two parts of the same object. In the case of the moon's effect on the earth, the side of the earth closer to the moon experiences greater gravitational attraction to the moon than the side furthest away, in effect 'stretching' the earth. The effect is greater on the oceans than on the solid earth.
The difference is gravitational attraction between Armstrong's head and feet are negligible, on the moon and on earth.

Answer 2

it starts falling torwads the moon
