Do can phones work?
Likewise, people ask, do Cup phones actually work?
The key is to make sure that the string is tight between the two cups, and this normally means that the distance is limited and the two people have to be connected to each other by a straight line. But as long as the string is tight, it works. It is also a great way to understand how telephones and radio work.
Keeping this in consideration, how far can a tin can phone work?
At around 650 ft., it may be the longest working tin can phone ever.
How to Make a Telephone with Cans
- Wash the empty cans – unless you want to get beans in your ears!
- Hammer a nail through the base of the cans to make a hole in the end of each can.
- Insert one end of the string through one of the nail holes.
- Hold one tin can, and give the other tin can to someone else.
