I got so excited when I thought of doing this activity -Um, hello! Cup and string telephones=childhood memories galore! They can also be used to teach communication skills!
They are simple enough to make--Just grab some string and plastic cups. Pop a small hole in the bottom of each cup (not any bigger than the string itself, you want it to be a close fit). I used my trusty exacto for this step. Now, lace the string through the hole, tie a knot--do the same thing to connect a cup to the other end (of the string) and BOOM! Communication tool. Eaaaaasy! If you have a kiddo who has never seen these before, watching their little faces light up with excitement when they hear your voice through a cup=priceless!
