diy water chiller?????

Anybody have plans for a diy water chiller? I'm tired of frozen bottles.

Simplest way. Put your air pump either outdoors or in a cold room near the elements during winter. The air pump will naturally use the cold winter air to cool your water. This will not work during the summer although. For the summer if you have an air conditioner just put the air pump in the air conditioning vent.

While that's good advice its not exactly what I'm looking for. But thank you for the input.

I'm thinking something like this. I have the mini fridge. Just curious how effective it is would be.
