Laser Tripwire Kit
Have you ever wanted to be a spy? Now you can, with this Laser Tripwire kit. This tripwire will activate and sound an alarm when someone (or something) breaks through the laser. Afterwards, why not add a camera or connect it to the internet of things? Protect your bedroom, or cookie jar, James Bond style.
