Help me with my Hamster!?

My guess is that the hamster is a bit confused and still getting used to her new cage. This happens to hamsters when introduced to new environment since they are creatures of habit. I am sure she would figure out herselves how to use the bottle in a few days, until then leave a water dish in her cage and make sure that there is always a drop of water hanging from the tip of the hamster bottle so that your hamster gets attracted to it and learns to drink from the bottle.
