You haven't tried everything to get your kids to study until you've tried the Study Ball. The Study Ball is a 21-pound prison-style device that locks onto your child's leg and only unlocks after a predetermined amount of study time has passed. The homework manacles can't be locked for more than four hours, and come with a safety key. The product website states, "Quite often, students who are having problems concentrating tend to get up every ten minutes to watch TV, talk on the phone, take something out of the fridge, and a long list of other distractions. Were they to dedicate all this wasted time to studying, they would optimise their performance and have more free time available. Study Ball helps you study more and more efficiently."
