Popcorn Kernel Jar Diversion Safe

About: Synth chick for electro-rock band, Former Human Beings

I recently visited a spy shop for the very first time and was very intrigued by their line of secret diversion safes. Most of them were cool but on the pricy side. Some of the objects were rather enticing, making me think they'd be taken if found (I know I'd take some WD-40). Others, like a can of Pringles, I'd probably toss right in the bin. (Goodbye, valuables!) Enter my cheap-as-hell jar of popcorn kernels. Just the right mix of "meh" to be looked over, and nice enough that only a meanie-goat with just throw it away.

Step 1: Gather Your Materials

You will need:

  • 1 empty water bottle
  • 1 jar with a wide top opening
  • 1 marker
  • scissors
  • popcorn kernels

Step 2: Prepare the Water Bottle

Peel the label off the bottle and dry the insides. Stick it inside the jar and use your marker to draw a line on it right at the lip of the jar. Cut the bottle right below the line. Discard (or recycle) the top of the bottle.

Step 3: Fill 'er Up!

Place the lower half of the cut bottle into the jar. Use your fingers to push the bottle inwards, then pour some popcorn kernels into the sides of the jar. Shake it in circular motions to fill any gaps. Keep filling until it looks 100% full.

Step 4: Store Your Valuables

You can now safely insert your valuables: money, jewels, keys, that 1st series Garbage Pail Kid.

    Question 2 months ago on Step 4

    I was going to make this for a couple of family members. I have the empty SMART water bottles but am having a hard time finding a glass jar for a good fit. Any suggestions for a good match between water bottle and glass bottle? The label is no longer on your demonstration jar so I cannot see the former brand/contents. Thank you.

    Hi there! The jar was the standard jar they sell at THE DOLLAR TREE in the jars department. It is a dollar and come in a square shape and a round shape. I used the square one. When I get home I can measure the lip and outer area for you to work out with your SMART water bottles!!

    That is wonderful news! I have some empty glass jars at home but none seemed to fit, the inserts were too loose or tight around the opening. I am thinking of making these for an xmas project-- a little side gift to friends and family. As an ICU nurse, many of my co-workers are SMART water drinkers so now I have several with two sizes of inserts, the larger one and a smaller one. I assume this one is for the 33 oz larger size SMART bottle? Knowing I can purchase a decently priced jar was a wonderful surprise. If you get a chance I would love to have the jar opening dimensions, so if I find something similar elsewhere I can take out my tape and check. Thank you again for all your help--your Instructable will be the gift that keeps on giving!

    Good information, thank you. I have mostly the 33oz bottles. I didn't know I could order the glass jars at Dollar Tree, thanks for the link and I can pick them up for free (!) at the local store. I will reread your instructions carefully again to make sure and measure twice-cut once. I am thinking of various jar fillers: Popcorn, rice, different colored beans or lentils, kind of mixing it up for variety and ordered small wrapped chocolates to be delivered in Dec to put inside the secret compartment. bow, tag and I will have my homemade share gift for work. I usually do a food item like Vanilla extract, etc, but this will be unexpected and fun.

    I believe it was the 33 oz SMART water :) It's the standard one I always see in the mini fridges at the shops; tall and pretty but not bulky. So I put the tape measurer from the outside lip of the opening to the other end and it was JUUUST about 3 1/4 inch. If you start from the outer lip (it's easier) and stop on the inside of the lip on the other side, it's 3 inches to the T. Remember that when you are pouring in the kernels, you will push in on the bottle to make space for it to be packed in tight! So as long as you can move it in with your fingers, you're good to go :)

    Clever! I have always thought that secret cans (WD40, paint cans...) could either end in a trash or stolen. As you said, your popcorn kernel jar is the perfect mix to remain safe!

    Same! I only know because I've had so many family members and ex boyfriends throw them in the bin, even when they're not empty :o

    Awesome idea! I used rice, and used a Gatorade "like" bottle with the large top opening, so I am able to put the top back on, and if needed cover the top with the rice (or corn!).

    The danger here is what if I forget about it? Would be like finding that $20 in your winter coat 8 months later! lol

    I like it! With these things, you do have to remember the sole purpose of the item. That's why when I saw the Pringles can at the spy shop, it was a pass because I usually throw those away. ;) I love finding that old $20!

    Great idea! One suggestion -- if you leave popcorn kernels (or various other grains) sitting around for long periods of time weevils may eventually hatch in them. Yuck! You can prevent this by putting the popcorn (or other grain) in the freezer for a few days before storing.

    I suppose... You could also put them in the microwave?

    that would probably work for other grains (rice, dry beans, etc.), but it would likely cause popcorn to pop. :)

    I love your addition! Smart. I know nothing of weevils and if I came across things that hatched, I'd faint. ;) Thank you!

    What a clever idea. I don't think even a popcorn-loving thief would bother to take something bulky that could be bought for about 50c a pound.
