Made this one years ago for Physics. It's nice to make it yourself but not very usefull
But I read that it should also be possible to hear people talk in another room when pointing the laser at a window and catching the reflecting bundle... because when someone is talking there it should make the glass tremble a little bit unfortunately I hadn't time to try it...
