This program estimate how far away a lightning strike is. Press and hold the lightning button or space bar when lightning strikes. Release your finger when you hear the thunder clap. **If you can hear thunder, you are close enough for lightning to hit you! Go indoors!**
This works because light travels faster than sound. You can do this less accurately in your head, just count "one-thousand" or "Mississippi seconds" and divide by 5. Update Log: Version 1.1 - Added metric and better controls (space bar or button for touchscreen). Counter is accurate to 0.1 second. (Counter is only for visual display and more accurate timer is used for calculations) Version 1.0 - Miles only, press lightning button then bell button. Counter is by whole number. (Counter is only for visual display and more accurate timer is used for calculations)
