Step

1

Tin canWash and dry two clean cheap tin cans. These are going to be the walkie talkies or telephones. Make a small hole in the center of each can making sure it has no sharp edges. It has to be large enough for the insertion of the string or cord, into each of the cans.



Step

2

tin cans with string on each canPush the string into each hole of the tin cans from the outside. Keep the string from slipping out by making a few knots in the ends. This will keep the string from slipping out of the cans when each person pulls their ''telephone'' or cellphone taut while you call someone and talk into it.



Step

3

longer strings allow for a longer distanceTalk into the can to the person in another room or in another area. The longer the cord, you can be a long distance from someone you want to talk to. Pull the string tight as you talk into the can. You will be able to hear and speak to each other. This 'Walkie Talkie', was also called a telephone and used by children communicating with each other and having fun speaking to their friends.
