The watering system utilizes the empty wine bottle, cork, and a small piece of tubing. A hole is drilled into the cork to hold the tubing in place, and the bottle is inserted into the ground with the tube pointed downward to water the plant roots.
This Instructable focuses on how I modified the cork to fit easily in the bottle and hold the tube in place. I was able to build these using materials around the hose, with the only exception being one quick trip to the store to purchase a length of tubing. With a $1.39 (plus tax) expenditure, I was able to make four waterers, which computes to a total expenditure of less than 35 cents apiece.
Step 1: What youâll need:
• Wine bottles (emptied of their yummy original contents), rescued from the recycle bin;
• Cork from wine bottle (I used one of the newer rubberized corks with great success)
• ¼ inch O.D. soft copper tubing. I found a two-foot section for $1.39 at a local big-box home store: http://www.homedepot.com/h_d1/N-5yc1v/R-202520516/h_d2/ProductDisplay?langId=-1&storeId=10051&catalogId=10053;
• A spare block of 2 x 4 to make the cork clamp;
• A small piece of ¼ inch wooden dowel.
• Drill press or hand drill;
• 7/8” spade drill bit and a 7/32” regular drill bit;
• Sandpaper (I used 150 grit);
• Tube cutter;
• Chop saw or table saw (used because they were available, hand saws would also work);
• Pencil and straightedge;
• Handscrew clamp.
