So, I am not completley blonde, and I do know how ice is made, but I have a curiosity about it. If I look at the ice cubes in my freezer, the bottom half of the cubes are white and the top are clear. Why is that?

Cloudy ice cubes result when water is frozen quickly. When water is cooled slowly (or very close to its freezing point), dissolved gases and microscopic bubbles have a chance to exit the water. However, when water is cooled quickly (further below its freezing point, a situation found in most home freezers), those small bubbles are simply frozen in place.
This is also due to the impurities in the water, usually minerals or chemicals. Try taking distilled water and freezing that and you should see a difference as well as something else - ice spikes.

I have noticed that too from time to time and probably has to do with trapping air bubbles in the water to cause the difference. it could possibly be caused by how fast the ice freezes as well that creates the entrapment of air in the water.Thre is certainly nothing wrong with the ice cubes as long as the water is pure to drink.

The "very small" oxygen bubbles settle to the bottom when the water gets cold and then freeze there.

Because the Bottom part freezes first...heat rises remember?

Are you using tap water? Sediment settles making them look cloudy.
