China Smart Drinking Water Pump Wholesalers introduces the process of making a homemade sprayer as follows:
Using waste straws and beverage bottles, first take two plastic straws with a diameter of about 3mm, heat one straw with a candle flame, and bend it into a 90° curved tube.
Then find a plastic beverage bottle, unscrew the cap, drill two small holes in the cap, and insert two straws into the cap holes.
The edges of the two nozzles are in contact with one point or leave a gap of 1~3(mm) to make a nozzle, cover it on the beverage bottle, and the sprayer is completed.
To use, unscrew the cap with the straw. Fill with an appropriate amount of water (limited to not submerge the jet tube), and close the bottle cap tightly. Hold the beverage bottle in your hand and press and release it continuously to spray water mist.
In the process of use, the water in the bottle gradually decreases. If the straw in the bottle leaves the water surface and cannot spray water, the sprayer can be turned upside down, so that the straw can be used as a jet pipe, and the curved pipe that contacts the water can be used as a water spray pipe, which can continue.
