In brief: Blood flow.

When your hands are elevated above your heart, the pressure in the hand veins is less than the heart and the blood flows back to the heart decreasing the amount of blood in the hand veins.
When your hands are lower than your heart, the reverse is true and the veins of the hands enlarge.

In brief: Normal appearance

When veins are lower than the heart, the hydrostatic pressure in them is increased.
When veins art at the same level as the heart or higher, their pressure decreases. Vein walls have a lot of stretch in them, in part to compensate for these changes in pressure. What you are describing in your question is the result of these pressure changes and vein wall stretch and is completely normal.
