Think about the reaction of sodium metal with Ethanol as well as about the pKa of Ethanol in comparison with the pKa of water...

...always start by writing a balanced equation...

If you add too much water in ethanol then you may produce enough heat and much nascent H2 which may flame your mixture or even explode it!!, so its very dangerous idea...If even use absolute alcohol you must be carefull when ading Na - never add big peaces of metal to avoid ignition or bad lab incident!
