So we did our experiment with the lifesavers. It was a lot of fun, standing in the dark in the bathroom with mints in our mouths. And by the way Breathsavers, Yuck! Turns out that we were both right. Wintergreen Lifesavers and Wintergreen Certs spark in the dark. Although Wintergreen Lifesaver spark a little bit more, we called it a draw. A win, win for both of us. So now it is bed time and we have very kissable breath!!
