Turn a Glass Coke Bottle in to a Plant Waterer





Introduction: Turn a Glass Coke Bottle in to a Plant Waterer

About: I like to make stuff. Whenever I go out I rarely buy anything because I always think, "I can make that". Here I will show you how I make whatever interests me.

Glass coke bottles are cool, really cool, but what do you do with the bottle after the coke is gone? You don't need any more candle holders, so make an automatic plant waterer. With this cheap and easy automatic plant watering system all you have to do is set it and forget it.

    Very nice I was In the glass Biz for years and cut many a bottles, by the way your website is expired the best to you my friend

    I love this project and your dramatic voiceover in the video! Very cool stuff. Haters gonna hate, but I think you've got a winner on your hands.

    Ditto! Thought it was awesome!

    I loved your video. I had all the tools (including the coke bottle), parts needed and put it together in just a few mins. I have lots of plants so they will be saving me lots of time. I love the voice over. Your video was as entertaining as it was informative. Thanks!

    Nicely done, but...
    - all the work
    - all the plastic
    - for a few ml water?

    Just take a big glass bottle (1l, 2 pints or bigger), fill it completely with water (no cap!) and ram it into the soil. Lots of water, no plastic. Works with sturdier plastic bottles as well. Only the very thin plastic ones will collapse under the atmospheric pressure.

    I take a 2 liter plastic bottle, drill a small hole in the cap, invert and put into the ground about 3-4 inches. Works for me.

    I agree. Or fill the glass coke bottle with water and just plug it in. It gives the same result...

    Without the cap water will drain out faster.


    The trick is: For the water to come out, air has to get in. Air can only get in, if there are air channels from the surface of the soil down to the opening of the bottle (i.e. the soil is dry enough to allow for air channels).

    Of course without the special cap you don't have a tube, so you have to ram the bottle in deeper.

    My sons both bought 6 packs of the small coke glass bottles and I made them save all their emptys for me!! I am excited to try this. Just need the caps and tubing. I have about 20 indoor plants now that I had to bring in my dwarf pomegranates, fig, honey berries and have an avocado tree started!

    "Yum yum" says the plant, heehee.
    Great tute, especially for someone like me who has a lot of potted plants!
    All y'all out there raggin' on this tute, get a life.

    Cool video, the voiceover was so unexpected, it made me laugh out loud!

    Hey! Im brazilian, and i used this idea here, great idea! Congratulation!

    Loved your idea. I used half liter, plastic soda bottles. They are working great. Saves me a ton of time watering each week! Thanks for the idea :)

    Like this!

    This may sound a little weird but also a woman's downstairs cleaning product "nozzle" would work pretty good too. Don't know why that popped into my head, i think it's because of the holes already in it. Great idea btw diygenius!! Sorry if my idea grossed anyone out. I figure you could also use a plastic bottle for it, say a 1 liter for larger plants. Thanks for the Instructable!!

    This is so neet, I bought one plant waterer did not work. This one is super.
