PREPARE to be astonished by “the world’s most dangerous circus act”.

No, not the man with the dog on his head (although the mysterious Mr N and his dog Speedie are a marvel to behold), but the extraordinary Globe of Terror, starring the South American Lucius Troupe who roar around their globe at “unbelievable speeds”.

Both acts are showing off their stunts at Zippos Circus, which has returned to Oxford’s South Park until Sunday.

Alongside them are Italian clown troupe The Rastellis and the acrobatic antics of the Timbuktu Tumblers.

And “legendary” ringmaster Norman Barrett MBE will show off his multi-talented budgies.

The show is on today and tomorrow at 3pm and 7.30pm and on Sunday at noon and 3pm.
