Stupid Cave Tricks

I almost forgot about something really cool we did in Tumbling Rock this past Saturday. We were about halfway back to the Topless Dome when we stopped to rest, grab a snack, and for a quick battery change. Morris pulled a bag of Wintergreen Certs out of his pack and gave Bob and me a handful. Then we turned off all our lights and sat there in the pitch black chewing up the Certs with our mouths open. They actually do generate sparks, just like I had always heard about but had never personally seen in action.
