This skill allows one to take advantage of Alexa when performing alternate foot bath (http://www.traditionalhydrotherapy.com/Techniques/AlternateFootBath.html). The skill (at least for now) allows to moderate "extreme version" of alternate foot bath - keep your feet in warm water for 10s and then in cold water for 3 s. Repeat the cycle 7 times but: - increase by 1 sec time to keep your feet in a warm water in each cycle, - skip putting feet ot a cold water in a last cycle.
