GREAT IDEA!! FOR BACKYARD FUN, NO BUGS!! All you need is a package of Mason jars, some cotton string and some liquid citronella (find it in big jugs at any home-improvement store and even some grocery stores). Use a hammer and nail to poke a hole in the top of the lid, then pour in the citronella, put the top on and drop in the wick. Allow the string about 10 minutes to soak up some oil.
Mason Jar Hanging Light DIY Project. This takes you to The Homestead Survival site which includes a link to the project (in Dutch) & a link for you to use Google Translate ;) This is what the opening paragraph translates to: "A low-budget DIY you can do even with two left hands!"
Cork candles. Finish your wine and collect corks. Then soak them in a capped mason jar filled with aceatone alcohol for a week. Light them up and enjoy making the easiest candle there ever could be. Happy summer!
