A Czech performer of bubble art surrounded 275 high school students and a car with a single soap-bubble screen on Wednesday, breaking the national record.

Matej Kodes raised the screen around a rectangular 11 metre-by-7.5 metre area, enclosing those inside for a few seconds.

Participants had to be taller than 156 centimetres (5 ft 1 inch) to fulfil the conditions for the event, which was supervised by a representative from the Czech Book of Records, who declared it a new record.
