Balancing Marbles

Attach the longest rung (7) to the bottom of a side rail. Note the position: the number should be on the back of the rung.

Attach the other rungs, number 1 will be on top.

Then join the second side rail and make sure the rugs are fixed tightly.

Remove the protective film from both sides of the plastic element.

Insert the last wooden part into the plastic one.

Fix the element between two rungs, then place the marbles in the holes. You can choose any level – find the balance!
