make music while you drink!
Everyone loves to blow bubbles with a drinking straw, but Fred wanted more! So we added a new, musical feature to the fun! Wet My Whistle is a reusable straw that works like a slide whistle - just blow to hear your melodious tunes. To drink, just block the whistle hole with your finger when you're ready to sip. Food-safe polypropylene construction. Includes (4) musical straws.
