5. Make Tiki Torches with Wine Bottle
Save those bottles and reuse them if you're an avid wine drinker. Connect a little bit of citronella oil and a wick, and you've got a cool tiki torch. Not only can they light up the night sky with a tropical flair, but during your barbecue, tiki torches will keep the mosquitoes away, too. Be careful not to make the wicks too long for you to have massive flames.
