The Aggravator Kit Skill Level 1.

 Simply place this kit in a hidden place in the room and it will wait in total silence until the room darkens. In the dark it begins its aggravating function: for about 2 or 3 seconds every 3 to 5 minutes it emits a screaming tone. Of course your unsuspecting victim will want to find the culprit so he or she will turn on the lights, but, the Aggravator Kit will remain silent again making it impossible to find. On returning to the quiet of the darkened room your victim will be startled again after 3 to 5 minutes of peace and quiet. This is a fun, harmless kit that will bring hours of enjoyment. Operates on one 9V battery (not included).

Complete with all parts, PC board and instructions. Size of PC board: 1 1/4” x 2 3/4”. Skill Level 1.
