aluminum can telephones

Time needed: 10 minutes
Skill needed: hammer
materials needed:

• string
• 2 aluminum cans
• hammer
• nail

This is a classic! I think every American kid for the past 4 generations has made one of these can telephones. The amazing thing is, they actually kind of work (as long as you hold the string tight)! (Although it doesn't make much of a difference if my kids are yelling into it anyway!)

Instructions:

1. wash out the cans.
2. Using the hammer and nail, poke a hole in the center top of each can.
3. poke the string through the top of the hole and tie a knot.
4. repeat on the other side.
   
5. play telephone!
