Christmas Present: K'nex Roller Coaster
My daughter and I just finished assembling one of her Christmas presents.
It's a K'nex roller coaster! And it works!
Assembly time was about 2 hours. We had fun putting it together.
If you have the parts to build it, add a chain tensioner. Just a little bit of extra force will help keep the chain on the track.
Fun!
