King’s College Choir Uses Helium    (April Fool's Day - 2014)

The renowned King's College Choir is not known for farce. This made it noteworthy when they released a video announcing that complex regulations had made it impractical to continue featuring young boys in the choir, and that they had been forced to find other ways to replicate the high pitch of the boys' preadolescent voices. Because the older choral scholars had vetoed the "surgical solution," the choir leaders had finally adopted a suggestion made by a colleague in the Chemistry Department — use helium. The video, demonstrating the use of helium during a performance, generated almost 1 million views on YouTube.
