"I'm starting to get dizzy. Me and Jerry have to fight through it and keep bouncing," Brott said.
In the beginning, the boys took giant leaps reminiscent of Neil Armstrong. Presumably, their legs will be much sorer after a day in the 13-foot-wide inflatable contraption.
By 5:25 a.m. today, the boys hope to have broken the record of 19 hours, 24 minutes set by Tom Williams and others nearly two years ago in Middlesborough, England. His advice: Mix it up.
"We found that if one person bounces for more than 45 minutes, then they feel very sore after getting off the bouncy castle," Williams said in an e-mail. "Keep changing the bouncer no matter how comfortable the bouncer may be feeling."
The boys planned to keep subbing in as teams of two changing at half-hour intervals, to keep legs fresh and lend moral support.
Mason has spent much of his short life dreaming of records, said his mother, Jeannie. He rounded up seven of his friends, who he knew either through playing Pop Warner football or as classmates at Chapman Elementary in Rockwood.
