This spring-well is also known as Heron spring-well and it was invented on antiquity. During centuries it suffers a lot of improvements so in our days you may easily build a spring-well using recycled and some other cheap materials.
First of all you will need two big plastic bottles of juice. Open one of them, drink, and continue to read. As you can see in the attached drawing you will need about 3m of rubber tubes as you use at your aquarium, some waterproof glue as acrylic silicone. If you don’t have this stuff around you is time for a trip at a supermarket, but first of all don’t forget to drink the whole bottle of juice. Now we have an empty bottle the other must be empty in the shortest possible time. We have the rubber tubes, the glue we need only a plastic bowl and a nozzle whence can be a part of a ball pen suited with the rubber tube hole. Make appropriate holes into the bottles slip in the rubber tubes add enough glue to be waterproof, fill the bottles with water (only half each one), drill the plastic bowl and insert the rubber tubes add glue , attach the nozzle. Put one bottle on a chair and the other one on the floor (about 1m between them), put water on the bowl in such a manner that only the nozzle to be out of the water. Enjoy it. When the spring-well stops just reverse the bottles position and put the nozzle on the other tube.You will see that the high of the water jet depend only by the level difference between this two bottles
