A new beauty regime for the boys

I purchased several glue sticks for the art projects at Sam's birthday party. In my need to take a "daycation" this week (okay, okay- it could be called a strike), I left some of the materials laying around. While I was on the phone, the boys were running around wreaking general havoc on the upstairs, and finally came dashing in with open glue sticks in hand, happily smearing them on their lips and face. I shrieked that they were NOT chapstick and to please give them to Mommy, which they did immediately. Then I got to thinking...do they make these strong enough to hold lips shut? Cause, my two boys have a SERIOUS case of the motor mouths. (Which they clearly get from their father ;-)
