Once these sparkly timers are shaken and set down, it takes about 2 minutes for the glitter to settle to the bottom. That’s the ideal amount of time kids should spend brushing to ensure they’ve thoroughly cleaned their teeth and gums. These fun timers not only encourage kids to brush their teeth, but they also help promote healthy oral care habits that will have positive long-term effects. You’ll only need a few simple supplies. This is a great craft to involve the kids–letting them make one right along with you. Once the timers are made, kids will simply shake, flip, and set them down to start the countdown to excellent oral care!
