Austyn loves this kind of thing. We tried it a few weeks previous but the wires we had were too thick for it to work well enough.
Thanks to a new friend who was moving and donated a bunch of supplies, we got to try this again and it worked great! The book I used is all about communication (I can't seem to find the book to share the title and I'm wondering if Austyn stored it away in his room). We learned that electromagnet was important in the development of telephones.
