A Marble Run With The Standard Building Set:

This one is easier than it looks, and really satisfying to watch.

Okay, so what do I need to do? 

  1. Starting with the base, grab these pieces, and arrange them about like this (plan to adjust once you put boards in place)

2. Put the 2nd, 3rd, and 5th longest boards like this (and use any shorter one for the other edge). Notice that the board marked 5 is on the blue and yellow supports, but leaves plenty of open space on the blue.

3. Now add the triangles to help the marble turn the corners. For me, they weren’t perfectly lined up with the board, be ready to tweak it once you get the next board in place.  In theory, you shouldn’t need the little red one, but I haven’t mastered that yet.

Place the two sets of elbows as shown.

4. Now, building up the support for the next ramp, a square on the end of each blue elbow (should now be the same height as the purple ones):

5. Then a green horizontal piece and a green vertical one:

6. Add the ramp—this is the longest building board, and adjust your pieces so that the board rests on each of the three supports:

7. And two horizontal and two vertical blue blocks (all 8cm long):

8. Two LARGE red triangles to help the ball change directions, and two yellow arches across the long ramp.  Note that the two yellow arches should be at the same height:

9. Add the longest remaining building board

Spaced so the ball rolls off the end and is caught by the large red triangles

10. To finish it, add two long green blocks between the yellow arches to act as rails on the top board, and two small red triangles as a ramp for initial momentum

Ready to roll!   If the marble is popping off, check the triangles to make sure they’re sending it in the right direction.
