Introduction: Anti-Theft Your Sandwiches

Picture of Anti-Theft Your Sandwiches

If you've ever been tired of people stealing your sandwiches (at school or work, for example), then here's a fun and easy 'ible for you!

Step 1: Here's What You'll Need...

Picture of Here's What You'll Need...

Here's what you'll need:

  • Sandwich bag
  • Green permanent marker
  • A delicious sandwich you don't want stolen

Step 2: Add Mold

Picture of Add Mold

Using your permanent marker, add some mold to the sandwich bag. This is best obtained by putting the bag on top of your sandwich so you can accurately place the mold marks. Consider where the sandwich will realistically sit once it's inside the bag (NOTE: this will NOT be all the way to the bottom seam of the baggie, but actually slightly above by about 1/2").

TIP: Mold is normally round-edged and organic in movement, so consider this when "spreading" it across your sandwich bag. Also, it normally isn't one single color. So darken in the middles of some mold spots by going over them a couple times to make new, darker "layers". You could even use multiple different green markers to make it more realistic if you want.

Step 3: Insert Sandwich

Insert your sandwich into the bag.

At this point, check the placement of your mold spots, and their coloration against the sandwich. Make changes as you deem necessary.

(I realized I needed to darken my mold spots in this step.)

Step 4: Enjoy Later!

Put your newly "molded" sandwich in your work or dorm fridge. No one will want to steal it now...but they might question why you enjoy moldy sandwiches ;)

Nice :) I just see a faces people who see you eating these sandwiches :D

Meglymoo87 (author)Lucas80002017-06-06

Hahahaha! That would definitely be a Kodak moment for sure! :D

A co-worker of my husband used to steal his favorit flavor of the donuts that HE bought for himself. He injected one with Ora Gel, and the thief thought he was having a heart attack. Hubby had to come clean before 911 was called.

Oh my!!!

Kudos to you, for coming up with an inventively effective way of discouraging the "work place hyenas" from scavenging your lunch. Most times all you need do, to protect your possessions from these parasites, is to make them "appear" undesirable. Where I work, a bottle of rubbing alcohol (used for cleaning) would regularly disappear from my toolbox, presumably "borrowed" by people too lazy to get their own from the supply cabinet. I relabeled a replacement bottle, with the "toxic sounding" chemical name for rubbing alcohol (dimethyl carbinol C3 H8 O) more missing bottles. Way to use your smarts, to keep what's yours :)

Meglymoo87 (author)maint12017-04-12

Aww thanks :) Hahahaha! That sounds like an AWESOME way to keep them off your rubbing alcohol! Brilliant!

Why is this not in the breakfast contest? And the colour blue has, from a psychologicall viewpoint, a bigger deterrence effect.

Meglymoo87 (author)Joerg Engels2017-04-06

Hi Joerg. It's not in the breakfast contest because it's not specifically breakfast related. And you should make one with blue mold! I'd love to see it! :)

Joerg Engels made it! (author)Meglymoo872017-04-11

Am I doing this right?

Meglymoo87 (author)Joerg Engels2017-04-11

It's looking good so far. I used a regular width marker (not thin/pen tip). But yeah, hoping to see your updated progress :)

Joerg Engels (author)Meglymoo872017-04-11

I used food colouring on a braid of a bread made with 8 braids. Didn't mix well with the dough, was displaced to the surface of the braid. Did you get my message btw?

Meglymoo87 (author)Joerg Engels2017-04-11

The one about my other apraxia ible? Yes, sir. But I don't have any good ideas as of yet. Btw, if there's anyone to bake the perfect "moldy" bread...It's you! When you perfect it...Send me pics! (I know you read this ible, so if you ever do one just on a baggie, let me know too) :)

Meglymoo87 (author)Joerg Engels2017-04-06

Also from the timeframe I put up this 'ible, there is only five contests available to out it in that aren't relatable at all unfortunately. See pics...

RayJN (author)2017-04-09

There many different bread molds from white to black and various blues and greens. See pic attached. Parmesan cheese mixed with appropriate food colors would make it more realistic.

Meglymoo87 (author)RayJN2017-04-09

Good ideas! You're right, you could go all out and transform the actual sandwich too! Please post a picture if you make what you're suggesting...Would love to see it :)

RayJN (author)Meglymoo872017-04-11

Yes I would put it on the bread. Have not done it, am retired so no one
to try it on except my wife who would just throw it out. But I may try
it to see how real I can make it.

The best would be to eat it in front of the suspected sandwich thief, but that would probably give away your secret weapon. It needs to be in a bag so it is only seen by the thief. Most people would likely just toss it without asking.

lemuries (author)RayJN2017-04-10

They sell lambs-wool in the foot care aisle that looks quite a bit like that white mold/fungus/whatever... if you go with the double-bag idea, you could slip it in between the layers and it would give it that 3-dimensionality too.

Bubblegumpop (author)2017-04-10

seems like a good idea. though, in my home if i try'd that i'd go do something and com back to see it in the trash

Meglymoo87 (author)Bubblegumpop2017-04-10


dmk1 (author)2017-04-10

Nice trick, but...

Generally speaking: You can't steal food more than twice from me without consequences :)

1st time - Might be a mistake

2nd time - Time for some laxatives :)

3rd time - They'll have a lot of fun sitting on the toilette seat :p

Meglymoo87 (author)dmk12017-04-10

Hahaha true!

StevenM135 (author)2017-04-09

Not meaning to out-do anyone but, I purposely scraped up my Suburban to detur thieves and vandals. It's surprising how other drivers will give you room in traffic when they think you don't mind a few dings ?

Meglymoo87 (author)StevenM1352017-04-10

Lol! That's awesome!

ocupmoc (author)2017-04-09

LOL, love it!

Meglymoo87 (author)ocupmoc2017-04-10

I'm glad you liked it :)

ElectroFrank (author)2017-04-09

More realism: Double layer your sandwich bags, put some crumbs and cheese in the gap, and -

Let it grow, Let it grow, Let it grow . . .

Genius lol! ? ?

Meglymoo87 (author)ElectroFrank2017-04-09

Lol! Great idea!

Ferntoe (author)2017-04-09

To steal is the deal. Don't worry about it getting thrown out...just be sure to have a few other personalized bags handy and make sure the office refrigerator police are through for the week. Otherwise, most people are scavenger hunters (it was just laying there)! Having worked ER, one of these scavengers plucked out a "free" sandwich...well laced with Maloxx. We figured out who it was real quick!

Meglymoo87 (author)Ferntoe2017-04-09


BrianR176 (author)2017-04-09

The joke will be on you when someone throws it out.

david-alexis (author)2017-04-09

This is the best dern instructable ever! Bravo!

Meglymoo87 (author)david-alexis2017-04-09

This is the best dern comment ever!! Love it! Thanks for the smile :D

jwzumwalt (author)2017-04-09

I wished I had thought of this when I worked for the Fire Dept. We had problems with folks taking foods. We had one fellow that would spit into his milk jug during shift change - he never worried about his milk being drank!

Meglymoo87 (author)jwzumwalt2017-04-09

Aww! Haha! You gotta do whatchya gotta do I suppose ;)

brgt40 (author)2017-04-09

This is great! It would keep many a sandwich from going "missing". But be careful clean-out-the-office-fridge day has past. HaHa

Meglymoo87 (author)brgt402017-04-09

Haha ikr!? ;)

ClareBS (author)2017-04-09

Really funny and it would work.

Meglymoo87 (author)ClareBS2017-04-09

I'm glad you liked it!

Jedi_zombie85 (author)2017-04-06

HAHA this is great, should grate some fine cheese on top to add to the mold look.

I think I can see an Contest coming up for "Worst Looking Edible dish" LOL

PattyP17 (author)Jedi_zombie852017-04-09

Ah! Very finely grated hard white cheese like Parmesan would truly add to the realism. If they opened to smell, one whiff would tell them the sandwich had definitely "died". Great idea!

lallerb (author)PattyP172017-04-09

I see halloween party food!

Meglymoo87 (author)Jedi_zombie852017-04-06

They should TOTALLY do a contest like that! Thanks for stopping by. :)

nanaverm (author)2017-04-09

A fun and practical idea, but the color is a little off. You need a greyer-colored pen.

Meglymoo87 (author)nanaverm2017-04-09

Yeah that may be true, depending on type of mold, location globally (aka climate conditions affecting your specific area), and type of material that is molded. My generic sandwich bread seems to always mold green where I live. Would love to see your rendition of it!! :)

joweeks (author)2017-04-09

nice job it does look gross lol

Meglymoo87 (author)joweeks2017-04-09


joweeks (author)2017-04-09

you posted this on my birthday

PattyP17 (author)2017-04-09

Maybe add a printed small tag that says "penicillin experiment"!

Meglymoo87 (author)PattyP172017-04-09

Lol :D Good idea!
