Make a Telephone
Teach your child how to make her very own telephone! The only materials you need are two cans and a piece of string. When you're done making it, explain to your child how the homemade telephone works. When one person talks into the can, the sound actually vibrates the string. The vibration travels down the length of string and the other person can hear what was said through their tin can! This is a great introduction to sound waves, and it's a great toy for her to use with her friends.
What You Need:
- Round tin cans (cover sharp edges with duct tape)
- Sturdy string, 6' to 8' long
