Editor’s Note: Released by Mag-Nif in 1980, Gravi-Tease were a line of handheld water puzzles designed to challenge players’ dexterity and spatial awareness. The compact puzzles mimicked the weightlessness in outer space, where “up was down and down was up.” Each puzzle featured small balls suspended in water within a sealed plastic frame. By tilting and rotating the unit, players attempted to guid the balls through a maze, with the water adding an extra layer of difficulty to the challenge.
