Instructions
Select the size of water bottle that you intend to use (either 3 or 5 gallons, the kind seen on water coolers).
Cut a hole, using your rotary tool (Dremel), in the bottom of the bucket to make a perfect circle. The circle should be wide enough to support the bucket and keep it from tipping over or being jostled loose. If there is a lip on the bucket, cut the hole slightly smaller than the lip so that it snaps into place when pressed onto the bucket. If there is not a lip, cut the hole wide enough for the bottle (when inverted with the neck pointing down) to sit on the top of the bucket.
Cut a small piece of innertube with a pair of old scissors to help form a seal around the hole, so that the hole does not leak air. Flip the bucket over so that the bottom part of the bucket is facing upwards. Duct tape the bucket in place so that it does not come loose when the water starts to run low.
Use the rotary tool again to cut the bucket so that the mouth of the water bottle (when the water bottle is inserted into the bottom of the bucket) is only 1 inch above the new mouth of the bucket. At the new cut, make an arch that is 2 inches wide and 1 inch high for the water to exit the bucket.
Remove the water bottle from the upside-down bucket. Fill the water bottle. Place the upside down bucket at one end of a 18-qt. rubber tub. Quickly insert the mouth of the water bottle into the bottom of the bucket and let the water chug out until the vacuum formed in the water bottle stops the water from coming out. Make sure that the mouth of the water bottle rests at the top of the water level.
