K'nex "Split Receptacle" Ball Machine

Introduction: K'nex "Split Receptacle" Ball Machine

This is my K'nex Ball Machine that I made in about 1.5 weeks with some help from two friends.  It is about 7 feet high and contains two lifts, two major paths, one minor path, and a roller coaster.  In addition, there are shelves on the other side of the wall it is hanging on.  I called it Split Receptacle because it is literally "split".  The top half is hanging from the wall and the bottom half is sitting on the floor.  They are only connected by small paths and chain.  It is called Split Receptacle because "receptacle" sounds cool and the term "split receptacle" is often used when speaking about electric curcuitry.  Although the video is rather dark, I hope you enjoy it!

    This is cool! I had a dream about a knex ball machine with a roller coaster built into it. I guess some dreams really do come true!

    thanks....the original idea was to have two roller coasters attached, but I had about 5 too few piees of chain. If you look close you can see two gears attached to the rod that has the roller coaster chain attached to it
