Introduction: Water Powered Clock

Picture of Water Powered Clock

This instructable will show you how to build a water powered clock. Here is what you will need.
1.zinc and copper leads 
2. connection wires(positive or negative)
3.3 bottles of water
4. low voltage digital clock display
5. water bottle caps

Step 1: Attaching the Leads

Picture of Attaching the Leads

Take your copper and zind rods and wrap the positive wire around the copper rod. Do the same thing with the zinc rod to the negative wire. 

Step 2:

Take your connection wire and connect one end of the wire to a copper rod and connect the other end to the zinc rod.

Step 3: Attaching the Leads to the Battery

Take your connection wire and put the copper end into the right water bottle.Take the zinc end and put it into the left water bottle.Take your digital display and attach the zinc end into the right water bottle.Take your copper end and place it into the left water bottle.

Step 4: THE END

do you need 4 electrodes? can you have 2 in one tank?

Where can I buy the digital display clock? I am doing this for a science fair project so could you please respond quickly?

beaver84 (author)thomas372016-04-06

I used an LCD out of an old watch, but you could probably find something on a DIY electronics website

thank you so much

Also..can you link a few of these power a small motor that could rotate a magnet through a copper wheel?..i.e. a round tube of copper with a slit on the inside of the wheen with a motor in the middle that would be able to swing a spoke around attached to a magnet around inside it? Generating more output?...

....or is my thought going against physics?

Is there a way to connect "already made consumer water"clocks and link those together for more power..that could charge a battery?


How much is this outputting?

where can I buy the copper and zinc lead?

beaver84 (author)kyniel2014-02-13

you can either buy them on amazon, or pick them up at a local hardware store

If you choose to buy them online, here are the links

Can I use an analog clock instead? Or will that affect the outcome?

bpanaguiton (author)bpanaguiton2013-04-28

Please respond ASAP :)

beaver84 (author)bpanaguiton2013-04-29

No, using an analog clock will not affect the outcome

Soo is there a step-by-step video tutorial ?... i would really appreciate if you posted the link

can someone make a step-by-step video tutorial?

beaver84 (author)gguevara12011-11-29

I will get right on it!

gguevara1 (author)2011-11-23

is there any alternatives for the zinc and copper rods?
can I use the powdered form of zinc instead of the rod?

beaver84 (author)gguevara12011-11-24

My prototype clock used + & - alligator clips connected to a copper penny and a zinc nail. But the + & - leads have to be made of zinc and copper. From what I know, there is no substitute.

hey beaver 84 that is so cool this is kat. :p

ZoDo (author)2011-09-25

Great job. But I think you should work a bit on the design. Give those bottles an artistic look.

punee (author)2011-09-24

For how much time does it work with 2 bottles of water, without changing the water.?

beaver84 (author)punee2011-09-25

I built it on August 26 and today the screen is getting a little bit dim, but it is still functioning properly.
