Water Bottle Hummingbird Feeder

Step 2: The cap hole

Take your drill, and using the 1/8 in. size drill bit, drill a hole directly in the center of the cap. We are using a drill bit slightly smaller than the diameter of the copper tubing. This way, when we fit the copper tubing into the cap, there won't be mush extra space. Water bottle caps sometimes have a little piece of plastic right in the center of the cap, so you can use that as your guideline.

When you finish drilling the hole, try to remove and excess plastic pieces that are in the cap.
