Introduction: Soda Bottle Sprinkler

The other day, it was over 100 degrees, and the little girl needed some summer fun. A lawn sprinkler would have been great, but I didn't have one. I headed to the recycling bin and pulled out a 2-liter soda bottle.

In my box of assorted plumbing parts, I pulled out a garden hose spigot. This one is designed to screw onto 3/4" threaded pipe. That's close enough to the threads on a soda bottle to just screw the bottle right into the end of the spigot.

On the hose end of the spigot, I threaded on a garden hose. This one happens to be a double-ended (female/female) hose, which is similar to a clothes washer hose. The female connection on both ends lets you connect the spigot on the soda bottle to a standard outdoor garden hose faucet.

I punched three holes in the soda bottle with an awl - two facing up, and one out on an angle.

Also, by adjusting the knob on the soda bottle, you can make it go from a high-powered sprinkler, down to a low-power drinking fountain!

  I later made another version of this sprinkler, which uses ONLY a water bottle as the sprinkler material. Click here to see the MK2 Soda Bottle Sprinkler.

    Wao

    and you can put holes in the bottom only and water plants evenly

    how much pressure can those coke bottles handle?

    I'm sure that if you have ever shaken a bottle of warm soda, you can feel how much pressure can build it. I would imagine that soda pressure is about the same as garden hose pressure.

    I don't think you have to worry about the bottle exploding or anything.

    Since there is a valve right on the end of the bottle, you can always use that to lower the pressure to however you would like it.

    They can handle 80psi fine, most homes are pressurized to 50-60psi. We had experimented with 2-liter bottles and had put them far out at the end of a long air line... they usually failed between 120 and 130 psi. If you stick to pressures around 1/2 of that... like the garden hose... no problems.

    Since you are using water which is non-compressive, if it did fail it would just rip and be fairly harmless. (Unlike high pressure air which expands with a boom.)

    So it should be quite safe... and a great idea if you have the parts laying around.

    If you want to know more about water and 2-liter bottles... I suggest you look up "Water Rocket" for some interesting reading and video.

    Great info, i know those bottles are tough but never thought to go blow some up with my air compresser. Well i guess i'll be out back testing soda bottles lol

    Just two points...

    1) They go KA-BOOM pretty good... makes a shotgun sound tame.
    2) You probably don't want to be within 50 feet of them.

    If you don't think the percussive energy release from one is much... think again. Just be safe.

    thamks askjerry, ive made a bunch of the "dry ice bombs" and yes they are very load when they go off! this was much safer and cheaper. the neighbors wernt to happy though. guess i"ll br giving it a little rest. maybe wait til after they arent so tired of all the fireworks
