Parabolic sound collector

This parabola can collect sounds in the target direction.
Please use voice recorder that connects microphone and earphone.
You need a recorder that can monitor the sound you are recording.

This one can be assembled but not worked very well.
Since the sound leaks from the gap of the parts, I need to think about a method to connect them more firmly.

Caution: Please use only for applications that do not touch the law.
