How do you get the last....

[Icicle]

Drop out of your bottles?

If it has a removable tip, pull it out and squeeze that sucker outta there!

Drop out of your bottles?

Take a full one, fill the empty one, now you don't have to worry about the last drop

Seriously though, how many half finished analogs did you toss in your lifetime?

Using a syringe and a blunt needle, you get as much out as you're willing to take the time to remove. I've "vacuumed" some completely, others get washed and new liquid mixed.
