Jelle Bakker made a Surprise Box for marbles (be sure to check out his You Tube channel.) I thought it was really cool, so I decided to make my own out of K’nex. (I am even making one for marbles!)

K’nex + Marbles is my first ball machine that uses both K’nex balls and marbles. The pink/red marble track is Skyrail. In an upcoming post, I will give more details about Skyrail. Below is the video. (Sorry I couldn’t get the marble lift to work on this ball machine). Sorry, I forgot to take pictures 😦 . See if you can spot a sloth in the video.
