Two tin or aluminum cans, or two papers cups Five-to-ten meters of string A hammer A nail Two tin or aluminum cans will hold up better than plastic ones. The string is less likely to tear through the bottom of a tin or aluminum can.
Each can will be act as a receiver.
If the first knot isn’t large enough to keep the string from falling out of the nail hole, then knot it again. If you’re using plastic cups instead of cans for your receiver, tie the string to the nail and leave the nail inside the cup. This will help keep the string inside the cup, as the string is more likely to tear a larger hole in the plastic. Make sure you secure the string in the first side before threading it into the other receiver since it will simply pull away from the first one.
Again, if you’re using paper cups for receivers, then you may want to get a second nail that you can use to help tie off the string.
Of course, you don’t want to pull so tight that the string breaks or pulls the string out through the bottom of your receivers. Just pull the string tight enough that you can pluck the string and it will twang.
Do not pull the string connecting the paper cups or aluminum/tin cans too tightly when using the walkie talkies. Too much force could cause the string to pop out of the cups or cans. If you make the receivers with tin or aluminum cans, be careful when placing your ear or mouth to the cans in case there are jagged edges around the lip of the cans.
If you don’t have access to a smart phone, you can always use the first method in this article. Push-to-talk apps are available for most major smart phone operating systems, including iPhone, Android, and Windows phones. [1] X Research source
iPTT: this is one of the App Store’s original push-to-talk apps. It provides one-to-many group communication. It also offers one-to-one communication within a group channel, called “whisper”, or straight one-to-one communication. It’s simple to use and free to download for iPhone users. TiKL Touch Talk Walkie Talkie: this is another simple but great push-to-talk app. All you need is your contact list and a data plan on your phone. TiKL supports group messaging and push-to-talk calls. It’s also free to download for iPhone and Android users. Voxer: this app functions like a walkie-talkie, but it sends messages rather than real-time dispatches. The app runs on iPhone and Android. It’s also free, and works over any data connection, including Wi-Fi. You can also send text messages, location messages, and photos. HeyTell: this app is a lot like Voxer, but with more customization. It has three levels of privacy, which allows you to add or block friends from Twitter and Facebook. Like Voxer, it works on any data connection. It’s free and can run on Windows Phone, as well as iPhone and Android. Zello: this app caters to developers, who want to add push-to-talk functionality to their own apps. But as a regular smart phone user, you can use Zello to turn your phone into a walkie-talkie. Like Voxer, Zello saves messages for replay later. The app is free and works on iPhone, Android, and Blackberry.
With the prevalence of smart phones, asking friends and family members to download an app is still easier than buying and sending them a walkie-talkie. Most of the push-to-talk apps also have group messaging, so you can easily chat with many people at once.
Since push-to-talk app use a very small amount of data on your phone, you can connect through the app without using minutes at all. If you’re connected to Wi-Fi when you use the app, then you won’t be using any of your plan’s data.
