This is a Rube Goldberg machine with a marble run, and it's very easy to assemble, so it's perfect for an 8 year old girl who is into Rube Goldberg Machines.
It took me about six hours to complete, but I could at least see that there were extra pieces when I was done.
It's really satisfying to see the puzzle come together in a way that makes you think, and I think it's a great teaching tool in the areas of mechanical engineering, gravity, and physics.
I need Piece D13 to complete the final step, but I can't find it.
I have thrown away parts of the board thinking they have been removed, but in the end, there is a small part in the cutout that I didn't know was there.
What is the dimensions of this item?
I don't have it in front of me right now but estimate that it's 10 inches long, 8 inches wide and 8 inches tall and my 11 year old loved putting it together, it also had extra parts I would buy again.
How many marbles are included?
There are 10 marble balls included in the kit.
Is it possible to order one part separately as a replacement for a broken part?
You can get new or replacement parts from the vendor, but you need to contact them via email or phone with the part numbers and a picture of the part if not numbered.
Do you have to turn the crank continuously after it is crank?
You just need to crank to carry the balls to the top of the stairs lift and it will roll along the track without any help.
