Items I used:
-Bowling ball (on hand)
-Tupperware cake cover (on hand)
-12" sewer pipe (found in a dumpster, but you can bury the cake cover in the ground and it will look just as good as those expensive fountains at the garden centers)
-PVC elbow (purchased)
-Plastic tubing (purchased)
-Small electric pump (on hand, Harbor Freight $9.99)
-Aquarium sealer (on hand)
-9" x 9" PVC bell drain (on hand, Lowe's $14.99)
-Decorative stone (purchased)
-Ceramic tile scraps (on hand)
-Concrete block (purchased)
-teflon tape (on hand)
-Duct tape (on hand)
-Chlorine or bromine tablet (on hand)
Tools I used:
-drill bits, various sizes
-Common sense. This instructable uses power tools and water. If you see nothing wrong with carelessly mixing these two components, please turn off your computer NOW!
Step 1: Getting Started
First, level the pipe and use the 1 1/4" bit to drill a hole about 6" above the ground for the pump cord to pass through.
The photo shows duct tape around the cord on the pipe but don't do that yet. You may have to adjust the cord to a workable length inside the pipe.
Step 2: Filling the Pipe
Placing tile scraps on top of the block was a trial & error procedure. The cake cover sat too deep in the pipe so I added enough layers of tile to raise the rim of the cake cover to about an inch below the top of the pipe. It will be covered with stone later.
You could fill the pipe with stone or gravel, but the block was cheaper, I already had the tile and if the pump has to be replaced, it's easier with the pipe being mostly hollow.
Step 3: Drill, Assemble & Test
Saw the corners off the drain so it will fit in the cake cover.
What I would have used if I did not have the bell drain on hand: 4" PVC coupling ($1.98).
Next, drill a 1/4" hole through the bowling ball. Use a bit that's long enough to go all the way through. DON'T try drilling from each side hoping to meet in the middle. What I would do differently: If you look at the bowling ball, there is a pattern in the swirls. I drilled through the thumb hole. If I had drilled through a finger hole, I would have come through the "top" of the pattern. The exit hole chipped a bit but it doesn't matter.
Next, silicone the PVC elbow into the appropriate finger/thumb hole & let it dry overnight.
As far as the tubing goes, I have no idea as to what size I used. I took the pump to Lowe's & picked up the PVC elbow, went to the tubing display and bought 1 foot of what fit in the elbow, and 1 foot of what fit on the pump. The tubes happened to fit together tightly when one was inserted into the other. I wrapped teflon tape around one end of the tube to make a tighter fit into the elbow. DON'T put too much stress on the silicone joint at any time during testing or assembly. If the silicone cracks, you have to clean it off & do that step over.
Time to test, which is easier on a deck or patio. The first photo shows how everything was prepared. The second shows the drain/ball assembled UPSIDE DOWN so you can see how it all goes together. Set the drain/ball in the cake cover, hook up the pump & add water. Plug in & stand back. You can swivel the ball around to get the water shooting straight up. Let it run a few minutes. If water splashes out of the cake cover, UNPLUG THE PUMP and enlarge the hole in the TOP of the bowling ball with a 3/8" drill bit. DON'T drill too deep! Drill in about 1/4" & test again. I had to do this several times to a depth of about an inch. The goal is to stop the splashing while maintaining a good spray height.
Photo 3 shows the chip in the exit hole and the swirl pattern I mentioned above. The bowling ball looks like it was used as a cannon ball but when the water is flowing, it looks highly polished.
Step 4: Final Assembly
What I should NOT have done: Notched out the side of the cake cover for the cord. I could have forced it. Tupperware has a lifetime warranty and if this one ever cracks, I blew it.
Photo 2 shows everything assembled. Fill with water & test again.
Now is the time to cover the hole in the sewer pipe with duct tape, sealing around the cord. I'm hoping that the combo of tape and the hole being 6" above the ground will keep critters out.
Step 5: You're Almost Done!
If you have "ugly" stone on hand, fill the bottom with that first. (Hey, I'm thrifty). I still used six bags of the decorative stone, probably the most expensive purchase for this entire project.
Now all I have to do is put a few plants around it & I'll be finished.
The water in the photo looks like it's splashing all over but, believe me, nothing splashes out.
I look forward to your feedback & will try to answer your questions.
