Krush of K'Nex

We are loving this video of the world-record K'Nex ball roller coaster, and you probably will, too. K'Nex are those cool, colorful snap-together sticks you can use to make giant shapes and structures. This one, built by Austin Granger, uses more than 126,000 pieces! Balls travel up little elevators, roll down wavy ramps, and ride ferris wheels, all of which together fill a huge warehouse.  See if you can follow all those balls, and guess how many sticks each one actually touches!

Make math the best part of the day.
