500 years of New-York history in 47 seconds
When you're visiting the One World Trade Center in New-York you can see a really cool animation in the elevator. To go to the 102st floor, you have to wait 47 seconds which is pretty fast because the building is 1776 foot tall. Yeah, 1776 like the independence day. Too bad Americans don't use the metric system... So, in the elevator, you can see how New-York grows since 500 years.
