Build Your Own Force Field Room Alarm
Sick of pesky snoopers barging into your room? Protect your space with an invisible force field! Just build the alarm and set the “force field” trap – an electronic eye that detects when someone comes too close. Build it. Stick it up. Activate the force field. One foot beyond the line unleashes a blood-curdling siren. You get privacy. Intruders get a red face!
Kit contains: 32-page security booklet, plastic case, 2 keys, sticky strips and electronic components for YOU to install.
