With soda bottles, compressed air and plenty of water, more than five-dozen Warren County Cub Scouts earned credit toward science and engineering merit badges this week.

The 64 scouts learned some fun, real-world applications for math, science and engineering this week during the annual Boy Scouts of America day camp at the Knights of Columbus Hall on Fisher Ferry Road.

“We had a pretty good crowd again this year,” said Boy Scouts volunteer Mel Malone.

Perhaps the most popular activity at the camp was rockets made of soda bottles.

“It’s like the Fourth of July,” said 10-year-old Nicholas Brown as one of the water-propelled rockets danced through the sky and rained down a stream of water and glitter.

“I loved it,” said Wesley Cowan, 8. “I got wet.”

Water was a central theme throughout the week. In addition to the water rockets, they participated in a Rain Gutter Regatta race where they boys had to guide a miniature sailboat with their breath.

They also spent plenty of time splashing around in the pool.

“I like the swimming the best,” said Mateo Byrd, 8, as he lined up to jump in the pool.
