The Human Spider
Most people take the elevator to the top of a skyscraper, but Alex Honnold prefers the outside route! Imagine looking out your 90th-floor office window and seeing a man waving at you from the outside. In early 2026, he became the first person to "free solo" Taipei 101 in Taiwan, which means he climbed all 508 metres of the building using only his hands and feet—no ropes at all! Learn more!
Wee Ones
Alex uses 2 hands and 2 feet to help him climb. If he reaches up with one hand to grab a new hold, how many hands and feet are still touching the building?
Little Kids
The Taipei 101 tower has 101 floors. Is the number 101 an even number or an odd number?
Big Kids
The Taipei 101 tower is 508 metres tall. If you round 508 to the nearest hundred, how many metres is that?
The Sky's the Limit
Alex climbed 508 metres in about 90 minutes. If he climbed at a steady speed, did he climb more than 5 metres every minute or less than 5 metres every minute?
