Are you about to start a spy mission and you don't know what you are going to need? To level up, you'll need a well-stocked kit. Gather the necessary elements and get to work!
Steps
Method 1 of 4: Gather the basic materials

Step 1. Choose the right bag
Your bag should both be big enough to hold everything you need and small enough that it doesn't slow you down or get noticed. A backpack or a satchel with many pockets will do very well. To avoid attracting attention, choose a bag in a solid, dark color.
- Also take a smaller bag with only the essentials that you can take with you if you need to leave the full kit behind.
- If you are wearing a costume, make sure your bag matches your character. A backpack or satchel can work in most cases, but if you're supposed to be an old lady, grab a giant purse instead.

Step 2. Bring a notebook and a pen
You will need it to write down your observations, codes or even someone's suspicious behavior. Try to find a small notebook that will not draw attention to what you are doing.
Write trivial things on the first few pages of your notebook. That way, if someone starts leafing through it, they won't realize right away that it's a spy diary

Step 3. Take a flashlight
Find a small flashlight or pencil light to put in your kit. Espionage often consists of sneaking around and snooping in, sometimes dark, nooks and crannies. A flashlight eliminates the need to turn on while avoiding bumping into the dark.

Step 4. Carry a roll of duct tape
Why that ? You can use a roll of duct tape to tape a message under a table for your classmates. You can twist it into a rope, use it to mend broken glasses, or even tie a bad guy's wrists. You can also use it to disguise yourself, for example by sticking dead leaves on your hat to camouflage yourself.
You can also use glow-in-the-dark tape to mark a passage for your classmates
Method 2 of 4: Communicate with other spies

Step 1. Make invisible ink
Make invisible ink and take some in a small bottle. Squeeze half a lemon then add a few drops of water. Mix the two liquids and pour into a small bottle to store in your kit.
- Bring cotton swabs so you can write with your invisible ink. You can also use a toothpick or a small brush.
- To read the message, hold the sheet of paper near a light bulb. The heat given off by the bulb will cause the message to appear.

Step 2. Take a walkie talkie
If you have partners in your spy mission, take a walkie talkie. This will allow you to call for help or warn your peers if you have any suspicions. You can pass the information on as you go, to your comrades in the field or to your headquarters, who will always know where you are.

Step 3. Make a coded message wheel
You may need to leave a coded message for someone. Cut out two concentric discs, one smaller than the other. Place the small disc in the middle of the large one and secure it with a Parisian tie or a thumbtack so that you can turn one disc against the other. If you're using a thumbtack, stick the tip into a small eraser so you don't get stung.
- Divide each disc into 26 sections and write the letters of the alphabet in order.
- Line up the letters on each of the discs: A with A, B with B, etc. To encode your message, choose a number and shift the central disk by as many letters. For example, if you choose the number four, shift the A over the E, ie 4 letters further.
- Code your message by finding each letter on the outer disk, but writing the letter that corresponds to it on the central disk. To write "HELLO" with encoding 4, write "WEPYX. "
- Remember to indicate the number of the coding to the person who should receive the message!
Method 3 of 4: Observe without being noticed

Step 1. Spy from a distance with binoculars
Stay away from the people you want to spy on. To do this, use a small pair of binoculars to observe them from a distance. You don't need heavy and expensive binoculars, which would only weigh your bag down and get you noticed. Find a small, light and inexpensive plastic pair at a camping store or discount store.
Choose discreet binoculars, in a neutral color (like khaki) so as not to attract attention

Step 2. Take pictures
Immortalize the actions or identity of suspects. If your phone has a camera, you don't have to do anything more. Otherwise, you can get a disposable camera to take pictures as the events unfold. You will only have to have your photos developed to obtain proof of the suspicious activity that you have detected.

Step 3. Watch your back with spy glasses
Spy glasses have small mirrors on the inside of the lenses, so you can see what's going on behind you without having to turn around. Get dark, wide-rimmed sunglasses with small mirrors glued to the inside of the lenses.
- Cut small pieces of mirror paper so that they can be glued to the inside of the lenses of your glasses. Mirror paper should cover the outer third of your eyeglass lenses.
- Tape the mirror paper to the inside of the glasses or glue it with a glue gun (for children, get help from an adult).

Step 4. Listen through the walls with the help of a stethoscope
You can use a medical stethoscope to listen through a closed wall or door. If you have an MP3 player, you can even adapt it to record conversations overheard with your spy stethoscope.
If you don't have a stethoscope, grab a drink and rest the rim against the wall. Do not stick the edge completely against the wall, slightly lift one side so that the sound reverberates outside and you can hear it

Step 5. Pack basic disguises
To be able to follow your target and gather evidence, it is sometimes necessary to disguise yourself. It will be useful for you to quickly change your identity thanks to accessories. Take a headband to hold your hair back and a beanie under which you can hide your ponytail. This way you can hide the color of your hair and also make it easier to look like a boy.
- Get yourself a pair of glasses. Sometimes that's enough to change their appearance and throw someone on the wrong track.
- To really change your look after hiding your hair, try wearing a fake mustache.
- Take a black or brown makeup pencil so you can easily draw freckles, moles, or wrinkles.
Method 4 of 4: Gather clues and evidence

Step 1. Assemble a kit for taking impressions
For this you will need a small container with flour, a thick, soft makeup brush (like a blush brush) and clear tape. To pick up an imprint, apply a small amount of flour with the brush, then pick up the imprint that has appeared with adhesive tape.
- Gently brush off excess flour with the brush. The imprint should appear clearly. Do not brush too hard so as not to blur the imprint.
- Use a strip of clear tape to raise the impression. Stick the piece of duct tape on black paper and bring it back to your headquarters for analysis.

Step 2. Bring some evidence
Use rubber gloves, tweezers, and small containers to collect evidence. Gloves will ensure that you do not leave fingerprints behind when you collect evidence.

Step 3. Take a close look
Take a close look at things. You may find small clues, such as a strange substance or a small colored thread. If a clue calls for close observation, use your magnifying glass. This will show you what others might have missed.
