Love it - this is the best reason to allow "smart" devices in the classroom.

I wonder - could it pick up the sound of a bouncing ball?

I'm still learning my way around Instructables. See the bouncing ball profile.

That was "great idea Kiteman".

Great I sensitivities kite man. You can set the trigger to any sensitivity. The closer to the baseline the more sensitive. I am sure it would pick up a bouncing ball. I knew it wouldn't take long for folks to come up new uses.
