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!
If you love the colorful glow, but don't want to mess with candles and tissue paper. Buy a box of glowsticks, cut off one end and pour it into the jar. Seal with a lid and shake to coat the inside. Voila! Instant lantern.
