Need help with jumping into water without having to hold my nose...Help?

Well for one your probably just scared your going to get water up your nose because it burns so bad and it makes me sneeze,lol. Try like tieng your hands behind your back with some rope and jumping in some five foot water or something.BREATHE out your nose,you can do it your brain is just telling you that you can't because of your nose holding. And you never no it might work.Just please try it.I see people do this everyday at a Private pool i go to and i cant stand when ppl do it. GOOD LUCK (: !!!
