Funhaler

 Gif FunbestThe Funhaler is an asthma medicine delivery device for kids. Traditional asthma inhalers scare kids into misuse (or non-use), but the Funhaler apparently "overcomes these difficulties by motivating the child to inhale willingly and effectively by the use of breath-driven incentive toys attached to the device, such as whistles and spinning discs."
