This window cleaner in Brazil became a superhero for a day, swopping his uniform for a Spider-Man outfit to bring some cheer to children at a hospital.

Vested with his new Spidey powers, he took on the responsibility of cleaning and abseiling down the glass facade of the Hospital Infantil Sabara in Sao Paulo on Monday - part of the celebrations to mark Children's Day in Brazil, which takes place today.

In a scene that could have come straight out of a Hollywood blockbuster, "Spider-Man" made his way down the giant building while greeting the children and joking with them, the Daily Mail reported.

In previous years, window cleaners have dressed up as Superman, Batman and The Flash.

Hospital bosses encourage the fun in the hopes that it might help children in the paediatric ward to relax.
