Check out this wonderful bridge designed by French artist
Olivier GrossetĂȘte designed for the Tatton Park Biennial in NW England - this year it was themed around the idea of flight.
Air
is what keeps this bridge up– or to be exact, three enormous helium
balloons, and though visitors aren't allowed to walk across the bridge
(it's more of an art installation), it would theoretically be able to
hold the weight of a person.
