Mark it zero!
I had something like this when I was, I don't know when exactly. My dad had hidden things all around the house and in the car or whatever. Each item I found had a piece of paper with a clue to where the next item was. I haven't the faintest idea anymore what the prize was (if there even was any), but I still remember this game to this day.

Maybe you could start hiding stuff around the house, with encrypted clues to other stuff ? On the other hand, maybe that's a bit much for an 8-year old, but what do I know, I have no idea how smart kids are at what age.

Anyway, this is awesome and he'll probably remember it for the rest of his life.

Instructables has a few instructions for making a book safe. That link actually has instructions for building a voice-recording module into the book too. If you've got the know-how, that might make things really interesting. "Your mission, should you choose to accept it...."

For making a book safe, I have heard, but never tried, that you can dunk the pages in some kind of glue (wallpaper, maybe?) while keeping the covers free. Once the pages are dried, then drill and cut the cavity. Epoxy or hotglue the bottom cover to the pages. In the instructables tutorial, they lined the cavity with self-adheasive felt. That might be a nice touch, too. Mind you, I've never done this but it sounds like it should work.

I used to love stuff like this when I was a kid. Here's some tricks for you:

Invisible Ink
Lemon juice makes an ink that is invisible upon drying - to read it, you have to heat it up, and it turns brown. Just squeeze a lemon into a glass, and apply with a softened toothpick or tiny paintbrush. Make sure to give him some directions to heat it included, like the "bress button, receive bacon" signs on hand dryers - a lightbulb should work fine, but ironing it works best (teach him how to use an iron?).

Delivery systems
- Cut a slice out of a tennis ball, and you'll be able to access the little hollow space inside. Perfect for a folded note!
- Wierd packages are ok to send by mail if they have proper postage on them. You could send a teddy bear with the messege hidden inside, with the the stuffing, or send him a trowel with coordinates scratched/etched on.

I would suggest including "secret-agent training" or "science skills" with your prompts, such as sending him a compass or protractor or telling him about vinegar/baking soda or coke/mentos (in which case, send him a funnel as "force concentration unit").

Everything up there should be pretty cheap.

Hollowing out the book isn't hard but if you still want more help (about gluing pages, etc.) visit an altered book website. Hollowed out books are loving AWESOME.

victorious posted:

This reminds me of a book I used to love when I was in primary school (mid-'90s): Alvin's Secret Code by Clifford B. Hicks. It was one of the most popular books among boys my age, its about a kid and his friends who learn about all different types of codes, both made up and ones that are used in real life, all over the place; and how to decode them. Even though it came out in freakin' 1963, I'm sure your kid would be into it, even though it is a little dated. Come to think of it, I'd definitely read it again if I ever found it...
Holy gently caress, I loved that book. I got my copy taken away at lunch because I was looking at the codes in back but the teacher was reading it to the class and didnt want me to read ahead. Nevermind I'd already read it twice! I was being BAD TO THE BONE!

But one code in that book is something I want to suggest. Take a long strip of paper, wrap it around a pencil or marker or piece of dowel, try to make it something unusual sized. Maybe a knitting needle. Secure with masking tape and write your message on it. Maybe make tic marks on one end where the paper meets up. Unravel, remove tape, send just the pencil to the kid. The next day, he gets the strip of paper with the code.

Bantaras posted:

Well, he DOES want a cat. We are planning on getting him one sometime soon, so maybe we can incorporate it into this thing. If anyone has decoded the messages you can see I have started with definite feline references...
Let his "final package" be a certificate to adopt a pet from the SPCA. (You can make your own or get one from them.) Package it like a "Please rescue me" message or something, or a "My mission is over, I'm ready for pick up, Agent Cooper!" Then he can go in and use his logic to figure out which cat is "his" and bring him home.

So he won't worry whether he got the right cat, work with the SPCA staff. If there's a cat he really likes but he's not sure it's the "right one," they can (with a nod from Dad) say, "Well, it's so mysterious, he just showed up one day out of nowhere with this note." And they show him the note, and it's written in the code, saying, "I'm the one--take me home!" Or he picks out the cat and when they hand him the adoption papers, there's one last note slipped in saying, "I'm the right cat--good work, Agent! I'll be maintaining radio silence for a while to keep our cover secure. Thank you for bringing me home!"

Holy gently caress I love this stuff. I wish my nephew was close enough to do this for him (he's 7). My neice is too old and too smart. :smith:

Buy a crappy old book and hollow the middle out and put an old cassette tape in there.

On the tape have the voice (use a changer program) say "NUMBERS EQUAL LETTERS" then have the voice read out strings of numbers, so "hello" would be "8,5,12,12,15,BREAK"

Then mail the book to him.

I think something like this would be pretty cool, especially if you had the book filed correctly and it helped him to learn how to use the library.

It also might be cool if you work with some other parents to get his friends into this.

Building a voice module sounds a little overly-complicated. Type whatever you want into notepad, then click start --> run --> and type "narrator". It will read whatever you've got on the screen in a super awesome sounding computer voice and you can just record that straight onto tape.

Ohhh oohh, instead of the cat being the agent, he could also be the "package" the Mysterious Code Sending Agent needs him to take care of. That way he won't be expecting the cat to have a decoder ring or anything.

I wasn't sure if my instructions were clear (plus I wanted an excuse to do it) so I did a visual for you. I used a chopstick and it worked out awesome. The tapered shape makes it more "unique," too. The tic marks are hard to see, but I did one tic mark for the top end and two for the bottom.

My message reads this is so loving cool will you adopt me

I'm not 100% sure, but I think AC Moore (arts & craft store) carries little chips where you can record your own message. They work like those music cards where you open it and the Star Wars theme or something plays, only you get to put whatever you want on the chip.

If you want to switch it up, you could send a coded message saying that the sender is worried the code may be compromised, and send a puzzle instead. Maybe something simple, like a grid and a list of coordinates to color in (I'm sure he'd ask you about the strange list of pairs of numbers) to create a few words or some monochrome pixel art, Picross-style. If you REALLY want to drive him crazy, send him the empty or partially filled-in grid one day, then the coordinate list a day or two later.

I think this is a loving awesome idea. 8 year olds can most definitely understand graphs if they're taught how to read and create them, but I doubt most schools do until a bit later on. This will give him a head start on that.

You should try to incorporate math somehow. Write a note saying that the code has been compromised, then give him a new key with numbers representing letters. Then send the next message entirely in equations, be it multiplication, division, exponents... hell, I bet you could teach him basic algebra. Simple things like 2^3 = ?, with 8 being some corresponding letter, or 6 - y = 4, with 2 being another corresponding letter.

He probably won't be able to do it by himself initially, but if you sit down with him and explain how to do a sentence or so there's no doubt he'll be able to finish it by himself, and in doing so learn some basic math that he won't be taught for another couple of years.

This is seriously cool, either way, and I hope I'll do stuff like this when I'm a dad.

That is going to be so loving cool and I can't wait to hear it.

Edit: Oh oh, another idea, inspired by the "code compromised" guy. Go to craft/arts/hobby store, buy small blank puzzle. They're like a buck or something. Use a sharpie to write the message on it. Break apart, hide the pieces around the house. (Or better yet, put them in little baggies, a piece or two each, and hide them around the yard or the park.) Kid gets message about code being compromised, new code is scattered around the yard/house/wherever, kid gets to go on scavenger hunt. He puts it together for his new code.

Might want to do two of those puzzles and keep one for yourself in case you forget where something was hidden.

I wasn't even thinking about MP3s or anything. I just figured you'd hold your tape recorder up to your speakers. That would also give you your static-ey, far away sound. It doesn't have to be fancy.

Games like these are great ways to trick kids into learning critical thinking skills.

Are you bilingual/near a border at all? Try the next one in a different language and see if he's smart enough to recognize/babelfish it. Or do it backwards. Or do it with no vowels. If you really want to get into it, just buy a PO Box and have him mail answers back his his mystery benefactor.

Also, be sure to make one of the prizes sports tickets or a baseball glove or something, so he doesn't end up a total dorkus malorkus.

When I was in HS there were a few families who would shop at the grocery store I worked at, very quickly I got the know the kids and I would have really enjoyed playing along with this. However, I had been seeing these families for quite a while, so if you do this make sure you know guy working.

I'm all for the hollowed out book idea. I would also go with the voice changer program, or that one tool in microsoft word that says whatever you type. Something tells me that he'd really love going to the library and getting the book. Bonus if you work it out with the librarian to have it held behind the desk for him. Coded exchange phrases are a bit cheesy, but I'm sure a little kid would love it. Plus, if the library story thread is any example, the librarian would love the break too.

I really want to see how this turns out now.

If you need some help with the audio aspect, I have all sorts of audio applications and filters, (as many of us do. Audition 3 plus a billion plugins) I have no problem setting up something to sound like a numbers station and producing it for you. I can then drop it on my site for you to download, or email it to you in mp3 form.

I want his messenger contact so I can get his mailing address to mail the kid postcards from another country, or send padded envelopes with tapes and CDs and pictures disputing the clues he's getting as if they are from the baddies and this other international organization needs his help to decipher the clues and codes they've been getting and that all is not what they appear.
