If the cap is cracked, then it shouldn't taste any less pure. If the cap is left off for a week, then it will taste less pure because of air exposed to the vodka
All grain alcohol is highly flammable and should be kept away from open fire!
For the best taste yes refrigerate. If it is not open you do not need to refrigerate other then before you use it for best taste but once it is opened it needs to be kept in the refrigerator as indicated on the bottle
It would evaporate over time but that would take many days. In my house it would last about 2 hours but that has nothing to do with evaporation.
Yes, vodka will evaporate when left out in the open because it is a volatile liquid that can easily turn into vapor at room temperature.

Well, honey, the ideal vanilla bean to vodka ratio for infusing vodka with that sweet vanilla flavor is typically around 2-3 vanilla beans per 750 ml of vodka. But hey, if you want a stronger vanilla punch, go ahead and throw in an extra bean or two. Just make sure those beans are split open to release all that flavor, and let it sit for at least a week before you start sipping on that delicious concoction.
