Freebase shouldn't dissolve in water, from what I heard (and experienced) even the salt can be a little difficult to dissolve.
Doing it "quickly" is no way to go, you are handling superpotent drugs that can be dangerous and deadly so chill the fuck down, do a lot of homework first so that you understand enough to answer these questions on your own.
Laying blotter drop per drop is also no decent way to do it, you will mostly get very uneven distribution of hits because people cannot drop like a micropipetting machine can and that can both be dangerous and confusing to people that eat the hits, causing them to redose times when they have a weak one (which can result in overdose), or they can overdose right away.
Check the Psychedelic Index, find the Big & Dandy Threads for the most common NBOMe drugs and read them front to back.
THEN maybe return to discuss something that could potentially kill people if done wrong.
