I haven't tested these in the rain, but I am impressed and slighted scared with how these trick candles stay lit. Note they do extinguish with a wet paper towel. So, rain may kill them too, but I think in the wind is where trick candles would shine. They seem to burn quite a bit faster than normal candles. I guess that's because the wick is thicker. They're small and light. I went ahead and packed a few of these in a car kit as backup.
