After my failure in my initial attempt at drilling a hole in a glass bottle to create a light of some sort, determination set in! I went to my favorite store, Home Depot, and purchased the glass/tile drill bits suggested for about $8.00.
I applied the lessons learned on the last attempt, and started the hole above the thicker bottom portion of the bottle. I also filled an old hairspray bottle with water to facilitate less mess when trying to keep the drill spot wet, but my surfaces dry.
After taping the bottle off, I started drilling. Very quickly, I realized that the right tool makes ALL the difference, but after another 10 minutes, I decided that this would be the 1st and last bottle I tried to drill through "for fun".
Being careful to spray the spot with water every minute or so, I drilled for about 40 minutes. I did have to stop about 25 minutes in to change out the battery in my power drill, but I'm not sure I started with a full charge.
The end result was still smaller than what I could get a set of Christmas lights through, so I walked away to think about it for a day or so. While wandering through Hobby Lobby with the BFF, I saw the small battery-powered LED lights and inspiration hit! I did have some of those from when Dollar Tree (my other favorite store) sold them at Christmas time, and they were small enough to fit through the smaller hole.
I had seen the glass etching cream ($9 Hobby Lobby) praised highly on several posts on Pinterest, so had purchased some to try out on the bottles. Since I was already doing a St. Patrick's Day theme party, I decided to etch Shamrocks onto the bottle.
Had to create the stencil for use, and the complete lack of directions on how long to leave on was disappointing. A search of the posts on Pinterest suggested about 1-2 minutes, so that's what I did. In hind-sight, I'll leave it on for 3-4 minutes next time.
Sprayed the whole finished bottle with spray on glitter, which isn't clearly visable in these pics, and turned on the lights. Not horrible, but wish I had left the etching cream on longer. Live and learn.
Time: 1 hour or so
