In this instructable i will show you how to make a hidden safe out of a large 6 volt battery. I will also show you how to make it give power to a light, even though it is hollowed out. ( that way you can prove it's "not fake")

Step 1: Parts

You will need:
Gloves, there will be acid in the battery
Tin Can
Pliers
Wire Strippers
Large 6 volt battery ( dead )
Soldering Iron
Solder
Copper Aligator clips ( 1$ for 10 )
9 volt battery
9 volt battery clip ( 1$ for 5 )
Metal Sheers
Tape ( scotch or electrical, electrical will be faster and stronger )
If you use scotch tape:
Black acrillic paint
Paintbrush or Sponge
Wire Stand ( or something to hold the wires in place )

Step 2: Step 1: Cut

Begin by using the metal sheers to cut away the top of the battery, be careful for sharp edges and acid.

Step 3: Step 2: Remove

Remove the battery contents by shaking it over a container, after emptied, rinse or wipe out the inside and the bottom of the cover.

Step 4: Step 3: Tape

Tape the edges of the top and the bottom with the tape you have. If you use electrical tape, skip to step 5 ( or step 6 in the corner ).

Step 5: Step 4: Paint

Time for childhood memories of mess and staying in the lines. Paint over the exposed tape in black, so it is the same as the top. wait for this to dry and continue.

Step 6: Step 5: More Cutting

Cut a small strip of the tin can and bend it up, put this to the side.

Step 7: Step 6: Soldering and Clipping

Take the battery clip, strip about 1cm off each wire, and twist these into the holes in the aligator clips. Solder the connections, and clip to the bottom posts of the cover. ( negative to negative, positive to positivee ). This is what will make the battery look real and light the light bulb! Now clip in the 9 volt battery.

Step 8: Step 7: Tape

Now take the tin can, tape the part you cut to the top of the battery, and tape the 9 volt to the side.

Step 9: Step 8: Install

Now put the whole assembly into the battery housing, and put in the top level with the sides.
Now you can hide valuables and money in your "safe". You can clip alligator clops to the battery terminals, and it will light up a small light!

Step 10: Video

This is a video of the safe, and how it looks.

Step 11: Final Note

This is NOT meant to be a super secret safe. To the casual observer it will look normal, but it is not the most secret, so don't post comments saying it doesn't look real, it is meant to be quick and somewhat effective. If you want a good , check my casset player safe instructable, and the modifycation instructable for that safe.

Step 12: Thanks

Thank you for reading my instructable, please look at my other instructables, feel free to post any comments or suggestion, any tips will be appreciated.
 the paint made it look really fake.no offence,good idea,but not executed very well.
just out of curiosity... why are you turning a 6V battery into a 9V battery? This seems like a good way to shorten the life of whatever you are connecting to it. You could easily achieve 6V output by using 4 AAA batteries and not compromising your storage space by very much. Otherwise, a great Idea!
Even more of a concern is the casual thief who tests all your batteries with a multimeter. He'll see that it's putting out 9V and know something is up.
Also very true, but this is meant to be stored in a very messy place, that is hard to notice it. I'm just wondering, do you know many people that will carry around a multimeter with them? :)
You mean like me? ;)
Yes, and they are quite unscrupulous.
not at all what i was getting at... but however you turned my comment into an a$$holism. thanx. be nice policy is only directed toward the author.... right? I thought i was pointing out something important, but you showed me that i was wrong. please continue to be perfect jake! sorry for existing
It was a joke, calm down.
I meant in no way to disprove your comment. I honestly wish I could have used 4 AA's, so please be proud to exist and live. As a robot I have only theorys on what it is like. Also, where did you get the name jake?
True, you could use 4 AA batteries, I would have done that, but I am lacking parts.
Typo, meant try
Please try one with an opening at the bottom, let me know how it works, I think I might TTY that when I find another battery.
"To the casual observer it will look normal," Not without the classic Duracel "copper-coloured top". I like the use of power in this to disguise it, but the finish isn't that good, you might have been better opening it at the bottom? L
True, it doesn't look very real, I was looking for some paint to mix up, but I couldn't get the color right. You could use a different brand, or find some paint at a hobby shop. I'm posting an instructable on making one out of the standard size 6 volt, which is simply a matter of removing the top. I will probably have it up today
