Directions for stacking blocks to make a harmonic curve:

1. Stack the blocks on top of one another, making a vertically straight tower. There are numbers on the blocks so stack them in numerical order.

2. Move the top block to one direction, until it begins to fall, then adjust it so that it is at the point where it lies flat but if pushed would fall.

3. Mark the wood with a pencil where the edge of the lower block is on the upper block, only if the mark is further to the left on the block than the previously drawn points.

4. Repeat all the steps until to the last block, if the blocks fall, restack them using the pencil marks as a reference.

5. Use the points that you marked to plot a graph.

-Make the Y values go in increments of one, so as to represent the one inch that it ascends.

-To graph the X values, use a ruler and measure how far the pencil mark is from the right side.

-If done properly the graph should show a harmonic curve as the relationship.
