You're right - I was assuming that there'd be at least one person in the group who knew what they were doing. For rank amateurs, closed cell is almost idiot proof (although I've seen Scouts melt them when I wasn't looking.)

To repeat from another post, in addition to telling my granddaughter to study hard, I gave her three other pieces of advice for starting her freshman year:

1. You can't drink them handsome.
2. If someone says "Hold my beer and watch this!" you should grab your cell phone and start taking video.
3. You can't fix stupid.
