We have a place in Cape Charles, VA that we restored and rent out as a vacation summer rental. After a night of beer and cards with neighbors, I was taking the trash out and remembered the empty bottles. Couldn't let them go to waste, but I didn't have anything to pop the bottems with. I looked all around and the only thing I could come up with was a 2 1/2 inch dry wall screw. I really didn't think it would work, but since that was all I could find I gave it a try. It took a bit of shaking, but danged if it the didn't work. Popped those bottems out clean.
