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

Faded Glory 😂 3.5 rating
Size: XX-Large, Color: Black-red, Size: XX-Large, Color: Black-red
Sooo faded I didn’t even want to try it on. And very dusty and ashy looking but only the red. It’s as if they had someone wear and wash it and return it and they took the red side and buttoned it onto another color and shipped it out. Guess these sellers like faded clothes. I wouldn’t buy certain colors seeing ppl talking about how the color doesn’t even last even upon its arrival. But if you have dye it’s your best bet to have some on hand when you order or even good for DIY projects.
Good thing is I did try it on and it fits and feels like good quality with good weight to it. May have to go up a size I’m a female with big breast. Seems like it may last, just not the color. Good stitch work buttons seem sturdy. Yea these shirts would be great for DIY work
