Kosmos Electric Alarm

The Kosmos Electric Alarm is an exciting experiment kit from the Take-Along Experiments series. With this kit, children aged eight and over can build their own alarm system with a working warning light and siren. The set playfully teaches the basics of electrical circuits and electronics. With minor adjustments, the system can even be converted into a Morse code device. An easy-to-understand, illustrated manual guides you step-by-step through the assembly, ensuring that secret hiding places in the children's room are secured in no time. Two 1.5-volt batteries are required to operate the alarm system.
