Here's a video of it to give you a better idea.
Step 1: The Tools and Materials
Tools you will need:
1.) a drill with uni bit
2.) needle nose pliers
3.) diagonal cutters
4.) About 50 feet of twine or string
5.) Something heavy like an old padlock to attach to the twine
Materials you will need:
1.) A 10 inch diameter acrylic white lamp globe. You can get them here www.1000bulbs.com for about $13.00 each. Get the ones with the extruded neck opening. You could concievably go bigger or smaller, but keep in mind that you will need more or less lights if you do. These are the exact ones I ordered:
2.) A multi color chaser light set with at least 140 lights. You can usuially find these at wallgreens during Christmas time.
3.) Craft wire, bailing wire, or some other suitable stiff wire for making the hangers. I used stainless steel aircraft lock wire, because I had some lying around the garage.
4.) A 50 foot outdoor extension cord. I used a dark green colored one that is hard to see and at night almost looks like the ornaments are floating.
5.) A fairly large tree to hang them from.
Step 2: The Construction
This is a pretty easy build; all you really need to do is drill some holes in the globe. The first hole is drilled through the bottom of the globe to allow rain water to drain. The last three holes are drilled so that they are evenly spaced on the neck of the globe for hanger wires to attach. An important note about drilling acrylic: go slow and allow the drill to do the work; if you push too hard you can easily chip or shatter your globe. Now fill your globe with the string of lights. Next, cut 3 wires about 10 inches long each and attach them to each hole bending with the needle nose pliers. Then twist them all together and make a loop to hang it from, and youre done. Just make sure you make the loop on your hanger big enough for the female end of your extension cord to fit through.
