The Independent Recommends: Events

DREAM ENGINE will certainly be praying for an un-blustery day tomorrow, since they will be hanging off a trapeze beneath a moving helium balloon, 20 metres up in the air above the National Theatre, as part of a day of free air-bound performance and street theatre. Momentary Fusion will glide through an elegantly choreographed aerial contemporary dance-piece, while Hi-Jinx fly through more circus routines. Bedlam Oz perform Slinky Love, a slithery courtship ritual for giant silver springs; while The Natural Theatre Company (above) schmooze along the river with deadpan expressions and daft costumes in their incarnations as alien Coneheads, or the grim-faced evangelists of "No Smiling Day".

Royal National Theatre, South Bank, London SE1 (0171-452 3327) shows run constantly from 12.45 - 7.30pm tomorrow
