Can you bring alcohol on a plane if you are underage?

Me and some friends are going to Hawaii for a senior trip and want to bring some alcohol since we cant buy it once we are there. Can we put the bottles in our checked baggage? Or will they know that we are underage? Also, could we put it in shampoo bottles, mouthwash bottles, etc. or will TSA check that and know it is alcohol. I know it cant be in our carry on because of the liquids rules, but is there a rule for liquids in checked baggage. Also, I know we are underage and could get in trouble. We dont care what you think about us drinking we are going to do it anyways so if you are only gonna say dont drink then dont leave an answer. Thank you!
