Keep groups of kids hydrated with Collapsible Silicone Tennis Ball water bottles from Maccabi Art.
Our silicone tennis ball water bottles make drink breaks fun for student athletes. When not in use, these eye-catching water bottles collapse into a tennis ball (3.5 by 4.75 inches). Expanded, they hold 18 ounces of liquid and stand 7.5 inches tall. The food-grade silicone contains no harmful chemicals.
These are good choices for the classroom, as well. Schools are increasingly allowing water bottles in classes, and these bottles are perfect for the job. The leak-proof spout prevents messes and spills, and a clip makes them easy to carry on a backpack.
