* glass Glass bottle (recylcling should be better, pet is pretty bad for you)
** can be simply mate bottle, the geeky feel is a plus
* water Water pump :
** the first solution is a hornbach water pump.
** Second solution would be a cooling system pump.

** We can even go further and use an mbed, or the serial port of [foo|Internal_Server].
* top Top and bottom reservoir of water
** No top reservoir should do it, we can add one after to normalize the water flow
* tubesTubes:
** some copper tubes would add a nice touch to the whole thing
** pvc tubes could be a simpler solution, but that wouldn't be that reliable under the heavy sun.
