Sometimes it is convenience that drives the experiment.
Find yourself on a Sunday late afternoon riding the bicycle, then the brakes spring a leak. Quick google search for the right product shows unavailable only to be had come monday or online order few days of shipping. Then the power of google searching reveals that baby oil might work. Hey whudya know, 24hr drug store is right there... Fast forward, "Dear Bikeforumers... look what I found!...."
