Power outage days are here in Los Angeles where it's so hot, people use their AC units all day and cause blackouts throughout the city. My husband came up with this idea to light up his sports drink with a mini LED light when I was frustrated it wasn't bright enough using just candles. You get a whole lot more light out of a tiny little beam this way. The greenish colour had quite the calming effect on me, as well! ;)

This would be great for the South during Hurricane season. Have 2 or 3 cases on hand.
