I need a 'six degrees of separation' starting from penicillin and leading to major inventions and historical events

For example

Penicillin leads to tuskegee experiments
Rosa parks was born in Tuskegee
Rosa parks leads to the civil rights movement
The civil rights movement leads to integration of schools
The integration of school leads to


Lonnie George Johnson (born October 6th, 1949 in Mobile, Alabama) is an American engineer. Johnson invented the Super Soaker water gun, which was the top selling toy in the United States in 1991 and 1992. Johnson holds a B.S inMechanical Engineering and a M.S. in Nuclear Engineering from Tuskegee University.


Or


Penicillin leads to saving soldiers in ww2
Ww2 leads to the invention of synthetic rubber
Synthetic rubber leads to latex gloves and, yes, condoms
Condom use leads to reduced aids transmission
Reduced aids transmission leads to the gay rights movement


But I'm a little stuck with my creativity.

Help?
