She and her husband had been our customers for several years. They made wine bottle and glass block lights. She sold them at their church's Fall Festival to raise money for an annual mission trip. But now, she was worried. This last year, her husband passed away. She didn't think that she could drill the wine bottles and block by herself. I explained that we have a simple way to drill glass that anyone can do. All she needed was her drill, the diamond drill bits and a kitchen scrubbing sponge. She cut a v-shaped notch in the end of the sponge and used the notched sponge to hold the drill bit in place. Water from the sponge keeps the bit wet and cool. Her Fall Festival was a success. Your wine bottle lights and glass block will be too. We didn't invent this wet sponge drilling. My dad showed me and we're passing it along to you. It's simple and it works. You'll make lighted holiday decorations. Easy drilling instructions mean that you can make wine bottle lights and lighted "Christmas presents" from glass block. As a bonus, you can use these bits to make bird feeders too. Diamond core bits drill holes in wine bottles or glass block in just 1-2 minutes. You won't break any bottles or glass block.
