Why would anyone need a diving board that is twice as tall as an Olympic diving platform? The Montreal Olympic Sports Centre has a 20-meter diving platform, to go along with their many other specialized swimming and diving facilities. It was cliff diver Lysanne Richard who talked them into adding the super-high platform. After all, they had room for it, and it's indoors where she can practice out of the cold. Tom Scott (who we know is afraid of heights) climbs up to the platform, but it's Richard who takes the plunge -after she sends her shoes down by zipline.
