I needed someway to provide decent feedback to the customers that could not be immediately delivered due to having to wait for the perfect weather conditions. After payment I would write out the message and store it till a day with the perfect weather conditions. I could send a picture of the message after it was written and I would post a video of the message burning and rising to YouTube. I tried it out and it only burns for 15 seconds which works out to about 240 messages in one hour of video. Their is very little ash after the message burns.
I also found a great site that sends a weather notifications when the wind is very calm.
