=How We Built It=

First we started by rapping construction paper around a marker. Then we rapped the construction paper with coil. We rapped the coil 120 times around the paper/marker. The coil transfers the sound waves into something that the human ear can hear.





That is what the finished coil looks like. However we couldn't remove the marker from the middle so we had to re-wrap it.

Then we got a razor blade. We needed to "blue" the blade, but we didn't have a blow torch. so we held it on a burner until it started to change colors. After we did that we dipped it in cold water to help it cool down. The razor blade works as the tuner, and when combined with a pencil helps change the radio frequency.

This is the razor blade after being "blued".
