The first person to ride down Niagara falls in a barrel and survive was a 63 years old dance teacher from Pennsylvania named Annie Taylor. Before taking the plunge, she launched a test barrel with her cat inside. The cat survived.
The stomping effects in the song "We Will Rock You" by Queen were created by the band themselves clapping and stomping. They then recorded the sound over itself (overdubbed) with delays to make it sound like many people are clapping and stomping.
