Accidents will happen – but few are as costly as the one that occurred in the Victoria & Albert (V&A) Museum recently.
The museum has been exhibiting the works of the world's premier glass artist Dale Chihuly, which sell at up to £2m apiece.
But just a few weeks into the show's four-month run, an electrician accidentally knocked into a plinth and sent one of the precious works crashing to the ground.
Luckily, Chihuly seems to have taken the breakage well.
His spokesman said: “The sculptures are glass and glass breaks.
“That's why we carry insurance.”
