While having a barbecue in Missouri this group of friends discovered that a cluster of flying gnats was responding to music and the sound of a human voice.<br /><br />Footage from June 12 shows how the insects respond to the sound being made.<br /><br />The filmer, Seth Phillips, said: "While in the back yard my fiancé makes a comment that the clouds of gnats are moving with the music. <br /><br />"Curious, we turn off the outdoor stereo and that’s when my buddy notices the gnats responding when someone speaks. <br /><br />"So I begin recording and he starts making different noises. <br /><br />"The result is what you see in the video; short noises make the gnats bounce and longer sounds make them scatter."
