Missouri corrections officials are testing a way to keep offenders out of jail by putting bracelets on their ankles.
But the bracelets won't be tracking the whereabouts of alcohol related offenders on probation or parole. The bracelets will test their sweat.
Every 30 minutes, 24 hours a day, a pump inside the bracelet will suck moisture from the offender's skin and detect whether he or she has consumed alcohol.
If they've been drinking, their probation or parole could be revoked. If they stay alcohol free, they could stay out of jail or prison.
