And , though most museums are happy to allow you to take photographs for private use , fairly high on the list of Things To Avoid Doing would have to be being so hell bent on getting the perfect shot that you back straight into a prize exhibit . Especially when it is a rather large vase . Specially designed for the room .

Though my favourite Oops museum story would have to be of the hapless clot who wandered over the Pindakaasvloer , a sculpture made from roughly 100 liters of peanut butter tipped over the floor and spread artistically by Wim T. Schippers in the Boijmans museum in Rotterdam . You'd think , given how it sticks to the roof of your mouth when you eat it , you'd feel the pull as you lifted your shoe . There'd be a fairly noticable " thwock " , surely ? .
