I saw this idea on Pintrest and thought it was great. I laminated mine and attached them to a sanitizer bottle with a Velcro dot. The bottles can be refilled. I also heard that if you put a rubber band around the pump it prevents children from pumping too much at once...brilliant! Students take the bottle and put it on their desk while in the bathroom. When they come back, they take a squirt and put the bottles away. I haven't tried them out yet, but have them ready to go for the first day!
