<p>I found the NY Times article. Here are a few quotes:</p>
<p>“In the course of a week, the 22 students at this session set off a wall of fire, blasted water out of a pond, blew up a tree stump and obliterated a watermelon. They set off explosive charges in the schools mine and finished off the week by creating their own fireworks show for their parents.”</p>
<p>“Dr. Worsey said that he saw his role in part as helping these students avoid the troubles that a fascination with explosives can bring. Many people who have been drawn to the camp, he said, have already made things like potato guns and flamethrowers. They could be one fumble away from injury or serious trouble with the law. And the camp, Dr. Worsey said, can give a nudge in the right direction.”</p>
