I would suggest sticking it in the freezer (mild chill so it won't freeze to ice), or in the fridge. Keep it in a sealed, tight container like a tupperware and then wrap it in more plastic. The sooner you use that urine, the better the results of your urine or the other person's urine. Source(s):

Actually, the Romulus and Remus myth originated sometime in the fourth century B.C., and the exact date of Romeâs founding was set by the Roman scholar Marcus Terentius Varro in the first century B.C. According to the legend, Romulus and Remus were the sons of Rhea Silvia, the daughter of King Numitor of Alba Longa. Alba Longa was a mythical city located in the Alban Hills southeast of what would become Rome.
