A refined version of Float Factor introduced in "Remember Here When You Are There!". What follows is a spoiler from that book.
First discovered when a bent spear rubbed against a Mystery Pod while Float Factoring, Float Force is the power that enables objects to float, and even move around, without needing to remain near a Mystery Pod or Twink. It powers both Floativation Stations and Chipskates.
Interestingly, it seems that Float Force can influence things other than materials made from the Four Realities. The Elusive Notworm uses it to send an Orbulator message from Gran'Ma'Pa off to Heyoka.
