This is what I do and it works perfect every time.
Put some duct tape around the top of the bottle cap making something like a bowl. Fill it with gorilla glue and let it dry (with your tube through the cap of course). The best bottles for me are Gatorade. I've had issues with soda bottle caps leaking air out of the sides. Gatorade seems to make a solid seal.
