Small Hand Generator Children Experimental Apparatus for Physics EducationFeatures:
.Clear Principle: The transparent plastic casing is for the clear observation of the internal structure and operating principle, manual rotation of the handle, through the gear transmission to the small generator, explaining the scientific principle that mechanical energy can be converted into electrical energy
.Simple Operation: Hold the motor in the left hand, turn the handle in the right hand, the motor can generate electricity, and the electric beads emit light. The faster the hand turns, the brighter the beads will be. The color of the screw joint is distinguished by red and black
.Stable Structure: There are multiple gears inside, the handle is flexible, and it will not be damaged for a long time
.Safe to Use: no-load output voltage: 6.3V output current: 0.2A; the product comes with a bulb, the bulb voltage is about 6 and the voltage is very low, which has no effect on the human body
.Can be used as a power source: Rotate the electric bead from the generator, replace the wiring, and connect to both ends of the power supply of the experimental electric appliance, which can be used as an experimental power source
.Note: Avoid moisture, prevent the coil from rot; not easy to use too much force, two turns per second is appropriate

The Perfect Digital Watch with all the Bells & Whistles!
Color: Black/Gray
I always buy this kind of watch, and so does my adult daughter. It has a timer, 3 alarm settings, push button light, easy to set, and other features that I don't use, like, track timers, Occasion settings, Beeps & Chimes, On or Off. I use it for timing my Laundry, taking pills, timing things in the kitchen. I just can't live without it! My daughter used it for timing on her Breast Feeding Schedule, so no matter what room she was in, or what she was doing, she would always hear that alarm!
