I know that it involves a suction thingy, and I have it, but I don't know how to actually do it. Help?
What I found in a quick search. Hope it helps.
But doesn't the suction thingy look like a baby thing they use to clean ears and mouths with? If so, I would take a wild guess that you squeeze it, put it over the tip and then release.
I'm surprised you didn't get any directions with it...
