Sweetie Pie: Mystery Weight Challenge (a.k.a. "Seesaw") - Using the left side of the screen, the player will select Tiny Toons characters to randomly match up (and hopefully outweigh) the computer's selections on the right.
In the theory of grand unification of particle physics, and, in particular, in theories of neutrino masses and neutrino oscillation, the seesaw mechanism is a generic model used to understand the relative sizes of observed neutrino masses, of the order of eV, compared to those of quarks and charged leptons, which are millions of times heavier.
