The molecule, finally. Notice how many zooms it took (6) to reach this molecule! This is a general rule though, partially explained by Tan Lei's theorum. It basically means the further you zoom into the froth the faster the molecules recede. In the next zoom sequence we will continue from this point to another molecule even further down. It will take twice as many zooms to reach the next molecule as the one pictured here did.

This doubling of the number froth chains is universal when zooming towards molecules. These 'x-way' crossings, such as going from 4 to 8 primary lines of froth (zoom #10), are interesting places. The froth chains combine in often unexpected ways.
