Step 3Drilling the Pipe
First measure the total length of the pipe. Depending on how long of a pipe you have, the distance between holes and number of holes will vary. I used 3 holes on each side with about 8 inches between each, and a 2 inch offset form the end of the pipe and the T connector. Don't make too many holes because the fog will not spread out as it should. Generally 3 is a good number per side.
Mark the holes and drill them. But remember; measure twice, cut once.
Once the holes are drilled you may have excess plastic around the hole. I believe this is caused by my drill having low power so your results may be different. Use a X-acto knife to remove the excess plastic and make the hole clean.
If, like me, you used a spade drill bit, when drilling the hole was completed, the bit punctured the back side of your pipe, cover that hole with foil tape to prevent fog from escaping.
