Britain's first indoor office helter skelter sees staff slide down three floors in just seven seconds

The economy may be on a downward spiral.

But designers of a new office development have come up with a novel way of lifting morale during the downturn.

They have installed a see-through helter-skelter to take staff from the third to the ground floor reception area in an exhilarating seven seconds.

Catering for media-related businesses, the Electric Works office complex in Sheffield opens on Monday, complete with the novel descent.

Made of steel and plastic, it is 87ft long with a 40ft drop.
