  3. Can a voice be heard around the world? Yes it can, you can call somebody with a phone and I chose this topic because how it travels is interesting.

  4. The phone came in 1876 when acid was spilled on a telegraph machine and the man called in his assistant to help him clean it up, but his voice was heard through the wires.

  5. When on the phone the signal, the form, changes three times. After it changes it travels along wires and poles, then it goes through an “entrance bridge” into your home all in under 5 seconds.

  6. The phone also aids in helping saving lives by getting help to those who need it a lot faster than if there were no phones.

  7. Phones can connect family by letting a little child talk to their grandma who may be thousands ofmilesaway.

  8. That is how I thought the phone was interesting.
