This is a water bowl for dogs or cats.  It is super EASY!  In a few simple steps you could have a water bowl that you only have to fill up once in a while, and it holds twice as much water for later on. 

In this project you don't need to buy a whole new bowl, you just reuse your dog's regular bowl.   If you are worried that you have to drill, nail, or put glue on the bowl, don't be concerned.  This project doesn't do anything to the bowl.

One important thing though, make sure you KEEP THE TOP OF THE 2L BOTTLE!

NOTE: This Watering Bowl was designed, built, and written-up to share on Instructables, by my 11-year old daughter. It's important that I give credit where credit is due, so any and all praise goes to her... the suggestions and critiques as well. It turned out really well, and I'm quite proud of the fact that she wanted to share how she did it here.  Nice work super girl!  What's your next invention going to be? #proudDad

Step 1: Materials

For this project you will need:

-2 by 4 piece of wood about 16 inches long
-1 by 6 piece of wood about 12 inches long
-2L bottle
-Dog dish
-Velcro tape (2 pieces of fuzzy sided, 2 pieces of hooked sided)
-Nails (3)
-Wood glue
-Wood clamp
-Spray paint or stain (optional)
<p>there are a lot of easier ones to make. This just seems like a lot of work for something so simple. </p>
Very cool project. My cat is a huge fan.
How doesn't the water level off and over flow?
Air pressure. <br>The water at the mouth of the bottle cuts off the air getting in as the water leaves, and with no way for the air to get in, that's that. <br><br>As the level drops, a little air will get in and the water then drops a bit, until the level stops the air again.
<p>Very impressed!</p>
Great job! One suggestion. Over time, any water bottle builds up bacteria inside. It's a tough film and doesn't come off even when you wash it with soap. It's good to either replace the bottle every month, or use a little bleach to sterilize it, then rinse it well. I know, gross. Of course, this goes for human water bottles as well.
A splash or 2 of Apple Cider Vinegar adds flavor &amp; minerals to the water &amp; also prevents bacteria from growing. But you have to slowly add it so your pet(s) get used to the new taste.
<p>Great idea, specially Braggs vinegar.</p>
I have some equipment that requires sterilization and I can tell you that a &quot;splash&quot; of vinegar won't prevent the bacteria from growing. As to whether occasionally vigorously shaking some pure white vinegar in the bottle would work, I don't know. The easy solution would be to use a new bottle every week.
The &quot;splash&quot; of Apple Cider Vinegar is mixed in with the drinking water &amp; it causes the water to be too acidic for the bacteria to grow. We use it in all of our animal water (bunnies &amp; both indoor &amp; outdoor water dishes for cats &amp; dogs). We used to have to rinse the outdoor dishes daily because they were gross. But after adding the vinegar we can wait until all the water is gone before rinsing the organic matter out. <br> <br>I even use white vinegar to clean the rabbit cages. It disinfects every thing with out chemicals that could hurt the rabbits. Gets rid of urine stains &amp; makes the cage look new! (Except the scratch marks on the plastic.) <br> <br>For *actual* cleaning your obviously need more than a small amount of diluted vinegar. And please note: this is NOT for hospital level &quot;kill everything with fire&quot; sterilization. It is simply a way to keep your animal's things cleaned.
Ok. Thanks. It really is impressive how versatile vinegar is for things. It never before occurred to me that pets could just get used to a little vinegar in their water. It's a good idea.
<p>Soda bottles contain so much sugar as to render the procut unfit for human consumption (diabetes, overweight, tooth decay, etc.). Perhaps some of this sugar remains embeded in the organic plastic after the bottle is rinsed. Try comparing the results with a plastic bottle purchased empty. The plastic is made from an organic substance and so might be delicious to bacteria compared to a glass bottle.</p>
I don't see the Velcro holding up for very long in the heat (if its left outside). I would permanently attach the bottle to the vertical plank, then have wooden dowels attaching the two pieces. Then it could simply be lifted to remove and refill.
<p>might want to get a different plastic if you're going to make it permanent. Plastic bottles are bad enough already.</p>
<p>Wow.. Cool</p>
<p>When making a similar rig for my cat, we found that the sipper from a rabbit bottle fit the 1ltr bottle that we were using. He very quickly caught on. At that point the bowl would simply be catching the drips. </p><p>Of course, the way the cat learned is from rubbing his face against the sipper. Don't know if the dog would have the same natural inclination.</p><p>Great rig! Good job!</p>
I'd have really enjoyed his reaction that first time.
<p>Great job. If you plan keeping it outside you should paint the bottle to keep algae from growing inside. If kept inside (no direct sunlight) it should not be a problem.</p>
<p>If you're having problems with too much water coming out then try drilling a hole in the bottle cap. Start out with a small hole then work your way to a large enough hole to fit your needs, plus you can cover the hole with your finger when refilling the bottle to keep it from spilling out...</p>
<p>Clever girl ;) Well done and thank you for the Instructable</p><p>Dad ...... what about the cap you advised to keep? Did I miss the explanation? </p><p>I intend to do this for my dogs as they do drink a lot of water but because one of their water bowls is in the bedroom by the radiator I'm just going to use that for the backing board :) Thanks again</p>
Well done young lady - keep it up! :) And awesome parenting! We actually have a future with parents like you!
Very cool. Thanks for sharing.
<p>Wish I could get my grandchildren to drink from it.</p>
I saw an almost identical setup on crazy Russian hacker.
AWESOME FIVE STAR SMART... except that you still need to refill the bottle. But you just need a bigger container for that like a gallon jar/ milk can... or like a gasoline barrel for lots (or really thirsty) dogs. Also, automatic food dispenser ( you could make it smaller for like a guinea pig or something). In fact, it's an automatic almost anything small/round/liquid dispenser!<br>
<p>much like InspectorD, my dogs would destroy this. Fortunately my spigot is placed such that a well calibrated drip keeps the bowl full and doesn't overflow much such that it wastes water.</p><p>That said, a nice addition to this would be something like adding a mechanism so that it self-replenishes with rain water (depending on your region). </p>
I made one, and now my dogs are afraid of drinking it because it'll make a noise when it bubbles! Smh
<p>smart! I would make this for my dog but she only drinks running water (from shower when someone holds hand for her to drink water from :)</p>
<p>Great instructable! I look forward to making this when our grandchildren come to visit.</p>
<p>FANTASTIC idea!!!! I have rescue dogs and this will really work great. I am also going to tell the Humane Society here about this too. I bet they make them for the dogs and cats. See you did something great for so many little animals :) Great Job!!</p>
<p>Nice going, girlie!!!!! Great idea, well-thought out, nicely built! (P.S. : thinking of an engineering career?? I'll write you a recommendation!)</p><p>Idea: instead of the several references to using vinegar to 'keep it clean' , why not try what we humans experience as one ingredient in most 'mouth washes' and/or 'toothpastes' :</p><p>Hydrogen peroxide! yea, a splash (maybe 5-10 cc's) of super-market H2O2 is pretty darn near 'sterilizing' and totally tastless! aND: when it 'breaks down' (you might notice tiny teeny-weenie-sized bubbles in the bottle over time, you get .. guess what: yup: waTER! And the bubbles are just Oxygen! The oxygen radical has been used to chew up germs etc , and of course any other material susceptible to it's action. For this, though, I'd suggest your parent get a rather large glass bottle of his/her favorite vodka, (NOT any plastic bottle!) and prepare the new bottle in the 'usual way' : yeah, empty it into that new plastic 2 Litre bottle bought for the project! Glass is inert (doesn't react with other stuff) and is easy to clean (suggestoin: get a 'bottle brush' from amazon, and let dad to the cleaning of the glass 1.75+ litre 'jug' ... </p><p>I can't even imagine how 10 cc's of H2O2 diluted in nearly 2 Litre's of water can possibly harm any living thing other than germs and fungi and bugs ... However, I logically can not assume any responsibility whatsoever for any or all risks to 'well-being' this might cause.. Be sure your parent makes the decision!) </p>
<p>Truely Great...</p><p>If I could add just one thought, use a wider water dish so the dogs head won't hit the bottle. Perhaps even a break loaf pan which is rectangular and long. Your dog might appreciate this.</p>
Tell your dad he's great :-)<br>Wish instructables was around when my dad was, when I was a kid-- we would have done a lot of projects like this together. <br>It's a great idea, owing mostly to its simplicity and harnessing a simple principle for perfect function. Great job!
That is good job , i love it .
<p>To support a heavy/full bottle you could add a U-shaped support to slide the neck of the bottle onto (at an angle) then fully upright to catch the velcro. That way the support carries the brunt of the weight and the velcro is there simply to hold it in place.</p><p>just a thought! great job!</p>
<p>HELP! I want to make something like this that will take 5 gallon Culligan delivered water. I cant believe such a thing isn't sold... but I checked and its not. The &quot;hduo&quot; product is the closest thing and they have gone out of business. I simply want to exchange the water jug every few 3-7 days or however long it takes for the dogs to drink that much water. There are plenty of 'refillable' devices, but they all get dirty and nasty and are difficult to clean. </p>
<p>Erin, I bought one of these for my dogs, and when I accidentally dropped and broke the 4 gallon jug that came with it, I was able to successfully use a 5gal water jug as a replacement. Hope this helps, they're great to use when you have 2 or 3 large water guzzling dogs :) </p><p>http://m.tractorsupply.com/en/store/petmate-le-bistroreg%3B-waterer-4-gal?cm_vc=-10005</p>
<p>this is cool not only is this a cool science trick but it helps with every day life</p>
<p>I think this is terrific. Just a couple of additional ideas. If you used a clear plastic tube attached to the bottle, you could then just attach the bottle to a brick wall (I want to put mine in the patio where it's cool &amp; I can keep an eye on it) ...so I thought I could just attach a piece of wood on the wall &amp; add the Velcro to bottle &amp; wood, or use a metal clamp (like plumbers use for pipes) that the bottle can just be dropped into it. Use a nut &amp; bolt on one side so that you can loosen it when changing the bottle, depending on how tight you want it to be. This would then allow you to use any sized bottle, as long as you can find a clamp to fit it. Then attach a similar, but small clamp, on the inside of the metal water bowl to hold the tube in place so that the animal can't push it out. This would be essential if going away for a day or two. You could also put a small hole in the top of the bottle (when upside down) to fit a funnel into the hole. No need to remove the bottle to refill this way.</p><p>NB Clear tube so that you can see if it's getting grungy ..&amp; cork or rubber bung to fit into the bottle hole for the clear tube. These should be easy enough to find at hardware stores, or just use a cork, or a drill a hole in the bottle cap.</p>
Very nice <br>But I wanted to ask something <br>I also made a dog water bowl filler but in my case i connected a hose to the bottom of the bottle and dipped the other end in the water bowl <br>It's the same principle but my bottle just crushed and all the water over flowed <br>The bottle crises under the vacuum created by water<br>What can do to stop it from crushing <br>Thanks
<p>If you freeze the bottle of water it will provide ice cold water for your pets</p>
<p>Nicely done!!! Many kuddos!!!</p>
<p>Awesome job</p>
have you thought of using a pice of hose like aquarium hose to go from the bottle to the bowl so that you can move the bottle back away from the bowl some so it isnt directly over the bowl like that?
No I have not thought of that. I think I will try it!
also i was thinking a box cover for it with a sight line to see the level for those people with cats and dogs that like to try to pull the bottle off the stand, just ideas was gonna tryt o figure out how to put one of these together myself for outside but this instruc. gave me a good base to start with
Cool! Made this, works well and only took me 20 minutes! Plus I didnt have to buy anything, so that was a plus. ;)
Hope this project was useful!
brilliant and easy to make! thx. <br>i've utilized the same concept for an automatic toilet bowl cleaner!!!
