    For those who actually paid attention in science class, please help me understand this.
    We fill the hummingbird feeders with about 1/4 c. of nectar, and it shows at the neck of the bottle. The next time we look, the bottle looks empty, but the hummers are still feeding from the reservoir. Then, the nectar reappears in the bottle's neck.
    Is this some kind of barometer phenomenon, or am I going nuts? Please do not answer the second question in the affirmative.

    Liquid in glass will look larger in an arched tube at different angles of light. <= (like I am a scientist):nerdy: Are you reading the level from the top or bottom? Your eyes may be playing tricks on you.

    Could be "capillary action" where liquid, due to surface tension can creep up the sides of a narrow tube (against gravity)

    I've used it to measure the strength of moonshine :whistling:

    Lillium, that is possible, but we are looking straight at the feeder, neither up nor down. Husband is going to do an experiment with an upside down soda bottle and see what happens.
    Zigs, I think you are onto something there--capillary action. I asked husband and he said that is quite likely. He also wanted to know how the moonshine came out!

    Well to give you a tip ! My grand dad used a soda bottle inverted in a canning jar to measure barometric pressure to decide when to go fishing ! If the water goes up into the soda bottle its time to go ! If not just watch TV ! Same with H bird feeders ! Just watch the barometer !
