Set this kit in an inconspicuous place with light shining on it and it remains perfectly silent. However as soon as the light is turned off the kit emits a high pitched irritating alarm tone! When they turn the light on again to look for the culprit it keeps silent! Easy to build and loads of fun to use. Show more
