Old Beer Bottles

We have a pile of empty beer bottles we've been saving up, and we think it would be sweet to somehow slip in each bottle and lights to string lights to put up around our apartment. Any ideas on how to approach it and get there? Thank you!

hey Ive just do it for my room. Get a string of white lights, drill holes in the bottom with a drill next dremal. Do not use a little metal crack and break the glass, just use a sanding wheel cone. then put the light in silicon and in place forever!
