Picture of Jar Clock
Here is a fun and easy way to make an unusual clock for your desk, office or just around the house.

This project took me about 30 minutes to make and cost less then $5.

I'll admit, it is hard to read the time, but it;s a great conversation starter, and looks neat and different at the same time.

I hope you enjoy (sorry for the poor photos), please leave suggestions and comments below.

PLEASE NOTE: I got this idea from Etsy.com. I am not taking credit for coming up with this idea. Just showing you how to make one yourself.

Step 2: Fitting the clock to the jar

Make sure the mouth of the jar is big enough to fit the clock base. I had to use my dremmel to take a little off the corners to make it fit.

I ended up just wedging the clock into the jar, and did not need to use any adhesives.

You can attach the base to the lid, but remember, you will not be able to turn the lid (think of a square peg in a round hole)

I also thought of using the dremmel to take the threads off the lid, and just snap the lid on (no turning needed)

IMPORTANT: you want to find a jar that has a circumference close to that of the mouth. If not you will have a hard time getting the clock hands in (and close to the wall)

Cheers. It's fun trying to watch folk try to tell time on it for the first time.

If I could save time in a bottle, the first thing that I'd like to do...

To make the hands more visible at night, you could dip the hands in glow in the dark paint.

Very Good idea, will do so on next model. Cheers
Where do you find the stickers that are black on both sides?
hey dude!
nice idea of making a clock inside a jar...

well i think you can make it more visible by increasing the diameter of the jar
as the linear distance every hand makes is directly propotional to the diameter of the jar...

do the math
and you can get an adequate clock
readability can be improved by decreasing the size of the numbers

and yeah
not everyone has this clock so take pride in saying that this one is yours...

see ya!
Very simple to make, thanks.

Aces!  Tops!  Best Instructable EVER!  OK...Not "ever."  But pretty darned close to it...

Super job...This will make Solstice gifting sooooo much easier.

Huge obsequious thanks...

This is so cool...off to make one now! Think I'll add a little something to the end of each hand so I can see better...really neat clock though!

Great idea.  Great Instructable.  And thanks for paying homage to where it is from.
Might I suggest smaller numbers all 'round?  Since it is a decoration piece, use just the hour hand like the first clocks ever made.  So you can see quarter past 1, half past 6 or quarter to 3.
Maybe put a smaller jar, hot glued inside with sand to isolate the hand from the background.

Just a minor nit-pick on Step 4 -- those are 90 degree angles :-)
pedla kelseymh4 years ago
as per the instructions:-nit-pic your nit-pic

The author properly edited the text of Step 4 to correct that error.

Elephants on acid, how many tabs does that take? I;m sure Billy Connely could do a great gig about that

   If you replaced the hands with long triangles it might make the clock easier to read.  There would be depth so you could see if the hand is point toward you or away.
elladan994 years ago
great 'ible! you are right, it would look better with the glass frosted but this looks pretty nice.

put a 5 wat light ulp in there and put on celing you got yourself a cheap projection clock
dude, i think it's cool.
there are several ways to make it better.
1. make the pointers outside the jar. Use fiber material.
2. Put some colored gel inside and LED
3. Attached a different color led to the center of the pointers.
4. Make the housing so you can put it on your ceiling.
this way you don't need to make rotating jar clock. it would quadruple your coolness if you do that :D

keep it up...!

cool idea but i think I have a better idea how to do it

id make it so the pointer was static but the jar rotates

very funny :O

Ha, no longer a child friendly project. will have to use 5 and 8 now

Pretty neat, but I have to agree that it does look a little hard to read. I think I'll just stick with the standard digital/analog clocks... 
scooter76 (author)  zascecs4 years ago
This clock does make you use your brain, and sadly somedays we can't be bothered, but I'm getting use to it.

Thanks for the positive comment.

I think it would be interesting to try to use a very light plastic jar and fix the jar on the hour hand. That way (hopefully) the clock could rotate the jar so the hour is always in front. The minutes would be relative to the front of the jar though not 12 as usual but that's not too big of a deal. Good 'structable though.
 How about a attaching the lid to a solid tripod? Or a larger jar? That was you'd have the jar roatating.


OH GOD IDEA!
have lots of jars. the smaller the jars get, the increments of time gets. you'd have a seconds jar, a minutes jar, a hour jar etc. That would be cool.

I don't think the quartz mechanism would be strong enough, need something more industrial or change the gear ratio but it would be cool. Or you could just ad an insert (paper or clear plastic to rotate and keep the jar stationary. Again many possibilities

How about attach a clear circular strip to the hands with the numbers on it and leave a clear window to read the numbers through.  OHHHH the possibilities...........

 Love it.

I love a good clock / watch mod.  This one is very inventive.  I find it a bit difficult to read the time though especially when the hands are on the other side of the jar... Thanks for posting!
