How cool is this? Grandma-ma loves this kind of scientific creativity. It is full of color and light and movement and all very well thought out. As you watch this vid, think of ways you would make the balls travel.
The builder, Austin Granger, says this
is his fifth major K'nex ball machine, and the largest and
most complex K'nex structure he has made to date. It took 8 months to build, has
over 40,000 pieces, over 450 feet of track, 21 different paths, 8
motors, 5 lifts, and a one-of-a-kind computer-controlled crane, as well
as two computer-controlled illuminated K'nex balls.
He filled is room with this structure. Wouldn't it be fun to go to sleep at night watching the balls move around and around? I hope you enjoy watching this as much as I did. Grandma-ma loves you.
