"It took several purple firecrackers exploding from the end of Professor Dumbledore's wand to bring silence."

This spell, described as causing "purple firecrackers" to burst from the tip of one's wand, was used by Albus Dumbledore to get the attention of panicking diners in the Great Hall when Professor Quirinus Quirrell revealed that a troll was loose at Hogwarts on 31 October, 1991.[1]
