Spray bottles are iconic household items. Whether you are spraying cleaners on a counter top or misting water on your plants, they are quite useful but they have some limitations. They can only operate when the end of the suction tube is submerged in the liquid. They have no problem as long the bottle is full and held upright. But if the fluid gets low or if you try to spray something at an angle, the sprayer might stop working. So, I figured out a simple modification that will let them function in any orientation.

By replacing the hard suction tube with flexible tubing and adding a weight to the end of it, the suction tube will naturally fall to the lowest point of the container. This will allow end of the tube to stay submerged regardless of how the bottle is positioned. Here's how to make it.

Step 1: Materials

Materials:
Spray Bottle
Flexible Tubing with 1/8" inner diameter (such as aquarium airline tubing)
5 x 1/4" Stainless Steel Nuts (or other weight)
Scissors
Glue (optional)
Glass beads. They make some fairly large ones with large holes. Try Michaels or Joann Fabrics. You could drill a hole in a soft rock even. Depends on how involved you wanna get. I imagine a hardware store will have some sort of pvc pipe fittings you might be able to use.
<p>Use brass or stainless nuts.</p>
<p>E&amp;C as... Easy &amp; Clever</p>
This is awesome! It's a real annoyance and I never thought of this. I wish all the people with so much common sense would post all their ideas. Thank you for putting yourself out there, I appreciate it.
<p>Go to a R/C model airplane hobby shop. They sell a weight for a fuel tank pick up made from brass or bronze. They also sell silicone tubing fuel line. Inverted flight still requires engine to receive fuel. I have been doing this for years. Thought it was common sense.</p>
<p>brass and bronze are copper alloys and react with chemicals to form poisonous compounds. Stainless steel is much less reactive, and rust is not nearly as poisonous.</p>
<p>What poisonous compounds exactly? I suspect they would just develop an oxide patina that would prevent any further reactions.</p>
<p>The patina is a mixture of poisonous compounds, most of which are poisonous, and most dissolve in water. This would include copper oxide, copper carbonate, copper sulfate, copper chloride. If the fluid is acid, like vinegar, it will react with the patina, leaving clean copper and poisoned liquid. All copper compounds are poisonous.</p>
<p>Silicone would be nice but not necessary. Stainless would be better than brass or bronze for reasons mentioned in posts.</p>
<p>You've been doing this with spray bottles for years? Impressive! I thought this was a pretty neat idea. Though I do think you make a good point about the silicone tubing--it is much more flexible than standard aquarium hose, which is actually pretty stiff and I'd be surprised if it would make a &quot;U-turn&quot; in the confined space of a narrow bottle.</p><p>Have you noticed any corrosion on the fuel tank pickups? I could definitely see (as EmmitS points out) some cleaners being pretty rough on these metals. Nitro fuel is probably pretty 'kind' in terms of corrosion....built in oil!</p>
<p>This is so brilliant that u should sell your idea :), Thank u for sharing :)</p>
<p>Brilliant. Thank you. </p>
<p>I have an idea for the 'weight' on the end of the tube -- the ball from an old mouse. Just drill a hole large enough for the tube to slide in. It will probably need some glue.</p><p>I'll let you know if it works, or I find something else, but it should work well. It shouldn't bang around so loudly.</p><p>I also think that I can get plenty of cheap, lab-grade tubing at the local college warehouse where they sell old supplies.</p>
<p>I can't help myself....</p><p>What did you do with the other one?</p>
<p>Since you asked... The mouse was from Flint, Michigan, and had lost one to the ill effects of lead in the water. The roaches, as would be expected, seem to have weathered the lead pollution better than any other life form because they have developed lead skin; they can literally plow head first through old drywall and they are very hard to kill. The mouse had broken teeth from trying to chew on them.</p><p>I hope that was the extent you're interested in mouse balls.</p>
<p>That is just awesome! You'd think manufactures would have gotten on to this ages ago. It would certainly prompt me to buy a different product, if the bottle had this advantage.</p><p>How about using brass nuts instead of stainless? Or dipping them in &quot;liquid handle&quot; type product? Guess it all depends on chemical reactions possible w/ contents of bottle.</p><p>Thanks for the idea!</p>
Actually. There is a commercial version. About a year after I originally posted this, the "As Seen On TV" people came out with "Invincible." It is a spray cleaner that has this kind of design. Every time I see it in stores, I wish I had patented it.
<p>The corrosion and other chemical reactions problem can be solved by covering the metal with silicone based glue/sealant. I will certainly do that myself :)</p>
<p>I'd try a lead fishing sinker or wrap a few turns of lead solder around the end of the flexible tubing. The lead could be coated with some Plasti-Dip (TM) if desired.</p>
<p>Brass (copper&amp;Zinc) and bronze(copper&amp;Tin) both, metal alloys of copper, are used on ships exposed to the corrosive atmosphere of the sea. They will form patinas that protect the metals from corrosion. A word of advice, &quot;Try not to eat cleaning compounds.&quot; Ammonia and chlorine are both poisonous cleaning chemicals. If you mix Bleach with Ammonia they will react and give off chlorine gas which will, in a high enough concentration, kill you graveyard dead. Silicone tubing is relatively cheap.</p>
<p>I wonder if you could use a two-part 'putty-type' epoxy? I think some of the heavier-duty ones are quite dense and are probably less reactive than metals. Might have to get a bit creative in getting it to stay fixed to the bottom of the tube--perhaps building in a bit of a bend at the end of the tube so that the epoxy weight can't slide off as easy. One could insert a temporary wire into the end of the tube as the epoxy hardens.</p>
<p>&iexcl;&iexcl;Muy buena idea!!</p>
<p>This is a very good idea for those of us who lack &quot;common sense&quot;. </p>
<p>Genius! Thank you so much!</p>
<p>Well done </p>
<p>Stainless steel is considered a non-reactive metal for food-canning purposes, so it much safer than other materials one might choose. Substitutions must be researched before using. Safety first in all things! </p>
<p>a true life hack. well done</p>
<p>a true life hack. well done</p>
<p>This is a great idea and I tried making it, but I wasn't able to get enough suction to pull the liquid all the way up with the bottle in the normal upright position, never mind upside down. Do you know why this would happen? I used a standard aquarium airline tube from petsmart.</p>
Check to make sure that you have a good seal between the tubes. What diameter tube are you using?
<p>This is amazing!</p>
<p>If your nuts are stainless steel, they won't rust very quickly if at all. Stainless has a high chrome content specifically for this. </p><p>This. is. brilliant. I am very impressed with this idea. Thank you for posting!</p>
Very clever idea. Perhaps instead of stainless steel nuts for weight you could use aluminum. It is lighter but I think would hold up better in contact with cleaners. My understanding is the aluminum oxidizes and this layer of oxidation prevents further oxidation. If you use the aluminum I would highly advise against using clorine bleach in the spray bottle. Clorine bleach and aluminum are a potential deadly combination. <br> <br>
<p>You're right. I'll bet that coating the steel nuts with plastic would fix that problem. Just dip the nuts in molten plastic. Or maybe even paraffin.</p>
caution using aluminum <br> <br>aluminum can react with certain chemicals to produce Hydrogen/Oxygen mix which can be explosive
Great idea! I always pour the glass cleaner out and make a big mess! One caution to All: when I was a house cleaner I thought I'd be clever & switch one sprayer for another. The tile cleaner that foams as it squirts out. Well, the traditional sprayer caused the tile cleaner to somehow choke me - the room filled with a cloud of cleaner - I ran outside until the room cleared! Didn't want the people coming home to find a dirty home and a dead house cleaning girl! So, please keep all tubes/sprayers with their Own chemicals to be safe. It was so scary. I was 19 and Naive! :)
Wow that is real y amaizing, i have alwas have trouble with that
brilliant........cheap and best........nice one......creative
Ahhhh YES! Simply clever! I make all my own cleaners in spray bottles and this tip will definitely save me that frustration you get when you're almost done with a job and realize you need to refill. Thanks!
This is awesome! I hate trying to spray sideways and upsides. Very nice improvement!
First off, well done! An elegant idea combined with clear video instructions. <br> <br>Regarding corrosion: Simpler than coating the weight and better than using stainless, I'd suggest finding some bronze hardware (not brass). Alternatively, given that strength is not an issue, you could also use lead, or even gold! On the less elegant front, a chunk of plumber's putty would probably also work.
Yayyyy! Thanks for sharing!
If you're worried about corrosion, you can coat the weight in some silicone sealer, then attach that to the flexible hose with more silicone. However, sometimes silicone doesn't adhere well to flexible things. So here is also what you could try: <br> <br>Take the stiff tubing that you clipped off, cut about a 0.5-1 inch piece of it. Cover your metal weight entirely in silicone/Sugru/Oogoo. After that dries, Oogoo the sealed weight to the side of the piece of stiff tubing. Stick your short weighted tube on the end of the flexible tube. Now you have totally sealed weights that won't fall off.
Fantastic! A lesson learned in how I think about problems: I saw just the title for this post on my phone without seeing the solution. The next morning this same answer came to me as I was waking up. So obvious once I knew there was a simple solution out there. So frustrating living with crappy sprayers. Thanks for the new tool and the life coaching.
I am at loss of words, simply brilliant :)
The weights shouldn't corrode much because cleaners are designed specifically as bases rather than acids to prevent corrosion on metal surfaces when cleaning them.
Ingenious. <br>Thank you. <br> <br>Where have you been all these years? <br> <br>I wonder if, as you say, the stainless steel nuts will rust could one not coat them with a lacquer such as polyurethane or even nail polish? <br>
Use type 316 Stainless Steel nuts. They have an increased resistance to corrosion and do much better in acidic environments. You can buy a pack of 100 from Grainger for around $30.
Thank you bishop14. A good suggestion with one minor drawback.<br>Let's assume I use 6 nuts to adapt the bottle. <br>What am I to do with the other 94 nuts? <br>$30 is quite a premium to pay for such a bottle even as good as it is.
You might consider using ceramic beads. Beads as in crafting etc... Or if you cannot find any - get a broken coffee cup or dish and shape/drill as neeed a piece...
