Good morning on this unbecoming Friday.

Because of a power loss affecting signals at 7 Av-53rd Street station, there are several service changes and delays on A, B, C, D, E, F, J, N, Q, R, B and M trains. Allow extra travel time.

The Coney Island Circus Sideshow is open for the season.

It’s one of the few remaining sideshows in America, where you can still be dazzled by a fire breather, spooked by a snake charmer or shocked by the human blockhead.

Among the band of performers in Brooklyn is Kiri Hochendoner, a sword swallower known on stage as Betty Bloomerz.

At 5 feet 4 inches tall, Ms. Hochendoner can swallow a 2-foot 4-inch sword.

And it’s not a trick.

“The scariest swords are the ones that stop right behind your heart,” Ms. Hochendoner said. “You can feel the temperature of the metal against that part of your body. It’s very sensory and you experience your organs in a totally different way.”
