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.
