The trick was performed Tuesday by Russell Fitzgerald, an amateur magician known to open meetings with a little sleight of hand. It was met with stunned silence.
The Enterprise of Brockton reports that Fitzgerald issued a written apology Wednesday.
He says he is sorry for the embarrassment he caused committee member Ellen Killian and his unwitting accomplice, teacher Steve Shannon. He also says he will no longer perform tricks before meetings.
Killian says she was shocked. The teachers' union says in a statement that Shannon was unaware of the trick Fitzgerald planned.
