And there I was, naively believing that the ballon sculptures in the Victoria Centre were floating freely within the capacious void of the building when, in fact, they are wire mesh frames to which are attached balloons, before the whole fakery is suspended from the roof by wires.
The balloons for this latest deception were being inflated by two ladies using machinery in the former Firetrap establishment in the background.
More details of this nefarious trickery here.
Update ====== Ten days later and they're still attaching balloons, though the balloon inflation facility in the shop has now gone. At least they've attached the lifeboats. Good to see someone with an eye on safety.
