Making your own spy gadgets can Darbi be a fun and rewarding experience. We tell you how to make a few simple spy gadgets that you can have fun with.


I have always been fascinated with the flashy gadgets flaunted by heroes of action movies. It often made me think how it would feel if those gadgets were for real. Well, unfortunately, or fortunately, not all of these gadgets are real. A few of these gadgets are available in the market, while there are a few that can be made at home as well. More than adults, I think kids love spy gear the most. Making these few gadgets at home will be fun for your kids and ensure some quality time with your kids. It is easy to make them and will be most liked by your kid, as kids like things made by themselves. If you want to send your friend a secret message and don’t want anyone to read it, then writing it with invisible ink will do the trick. Well, the ink itself is not invisible, but after writing with it, it becomes invisible. To make disappearing ink, you will need few chemicals.

First, you will need to put 1/10g of thymolphthalein in 2 tbsp of rubbing alcohol. Then, add approx 90 ml of water to it and stir. Once you get a little thick solution, add approx—20 drops of sodium hydroxide. Once you’ve done this, the solution will turn dark blue. You’re disappearing ink ready! To test your solution take a cotton fabric and write anything on it with your disappearing ink. After some time, you will see that the ink has disappeared. To reread the message, dab with ammonia over the message, and it will reappear. Writing on paper takes more time for the ink to disappear than writing on fabric. For this, you will need lipstick (best if it is empty) and paper. You need to cut the paper to a rectangle 10 inches long and 1-inch wide. Write your secret message on it and coil it. Insert it into the lipstick, and you can now smuggle your ordinary-looking lipstick with the secret message.


This one would be liked the most by little detective spies when looking from the door keyhole is not enough. To make your own spying keyhole, you will need thick paper, a very clear marble, and sticky tape. First, place the marble on the paper and roll the paper to make a tube out of it. Stick the paper with sticky tape so that the marble inside it doesn’t fall out easily. Try to place the marble in the center. And here is your spying keyhole is ready. It is imperative to use marble as clear as possible to get a better view. Also, because of how light is reflected through marble, you may get an inverted image when you see through it.

This can be the easiest of all. For this, you will need a walkie-talkie, a remote control car, and glue or sticky tape. For better range, use a good pair of walkie-talkies. What you need to do is stick your walkie-talkie to a remote control car. Make sure that your remote control car can take the weight of the walkie-talkie and maneuver effortlessly. To hide the walkie-talkie, make a design out of paper to hide it. Let the walkie-talkie remote control cargo to rooms where you want to spy, and you can listen to the conversation with the other set of walkie-talkies you’ve got.

Spy Hidden Camera

Spy cameras are interesting devices. To make your own hidden surveillance camera, you will need an empty tissue box or any other disguised box, a digital camera, and a knife or scissors. Cut the box’s side so the lens of the camera fits in it and full images are captured. Place the digital camera in it with the camera’s lens just in front of the hole you made and make sure that it cannot be seen. You can cover it with some tissues to hide it. When you want to spy on somebody, keep the camera in recording mode and get your evidence. Spy gadgets like the ones described above are easy to make and help you spend quality time with your children. However, ensure that along with teaching them how to make these gadgets, you have to teach them to use them appropriately.
