The tongue can not be made longer really. You can try and stretch it out to try and make it longer. Your tongue is the strongest muscle in your body. For more info see link. http://www.funadvice.com/q/longue_tongue...
Then again, this answer might help you...
You can't make your tongue longer. There are no exercises that will give you an elongated tongue. It's genetic and is predetermined by your parents. Gene Simmons has one of the longest tongues in the world. Rumor has it that he had surgery to make it longer. He denies it!
