Bowling was invented to contradict Galileo's findings, since it demonstrates that the movement of spherical objects is relative to the position of pinheads. Teach those geocentrists a thing or two about physics with today's Groupon to Hiline Lanes in Burien. Choose between the following options:

• For $14, you get three bowling games (up to a $25.50 value) and shoes for two (a $6.50 value; up to a $32 total value).
• For $18, you get admission to Friday and Saturday night's glow-in-the-dark Rock -n- Bowl for two, including two shoe rentals (a $36 value). Rock -n- Bowl hours are 11 p.m.–1:30 a.m.
  
  

Hiline's pro-grade equipment sends pins scattering as couples compete to hone skills or have fun, supping on American diner fare from the kitchen to the sounds of jukebox tunes or tandem bowling under black lights to raucous pop beats. Bumpers even the odds for players of all skill levels, unless those players are shot-putters or geometry majors, and bright-red-and-blue shoes hug feet in a frictionless embrace. On Friday and Saturday nights, the fluorescents cut out during Rock -n- Bowl, letting neon and black lights suffuse the alley with an otherworldly glow as the speakers roar with the latest hits and glow-in-the-dark bowling balls wreak merry havoc among pins or assist in finding lost keys.
