Yep, just direct that water flow (drip) where you want it. I wouldn't let it just touch the ground, because being aquarium airline tubing it's pretty narrow and might get clogged up with dirt.
Then I would daisy chain the containers, put one above the other, let it drip into that container. Or, go with something larger than milk or soda bottles (I'm all about cheap to free, ya know?). Maybe something like a cheap 5gal bucket would work better for you.
This is how recently arrived fishes are acclimated before being put either on store display or into warehouse holding tanks. The fish go into pans (often kitty litter pans), we set up the container with the shop water, set the drip anywhere from just a few drops an hour (a little tougher to regulate) to a steady stream. One drop per second is my personal preference for fish acclimation.
