Going to substitute, need quick answer

OK so I am going to take a test really soon. I have my bottle of quick fix and it takes about 45 minutes to go from room temp to 94 degrees under my taint, so i have that part figured out. what i was wondering is, the bottle comes with two lids; one of them has like a little flip up nozzle or whatever so you can spray it in there. my question is, do I really need to spray it? my only concern is that if i spray it in there, when it gets to the end it will give that kind of "wheeze" like an empty bottle does and someone might hear it. i would rather just pour it out of the bottle, but i thought that they might check to see if its froths up or whatever like when you piss into the cup. can anyone help me?

ok well i am just going to pour it

I was kind of wondering the same thing.

bring a straw with you and blow bubbles in it

or shake it

I didn't use the bottle top. I just poured it in.

i used the pop up but here is a tip most test now are 6 ounces and those are usually only 4 so make sure you have at least 6 ounces especially for lab corp testing. and the top does not make any noise.
