A real life Eyedropper tool! This is awesome. A pen with a little censor that scans the color of the object you point it at, then you can write in ink that exact color, it's like the eyedropper tool in photoshop outside of the computer.
Use toilet paper rolls to start your plants. When ready to plant, stick the whole roll in the ground. Roll will decompose.the toilet paper rolls got moldy before the plants grew. I will stick with growing my seeds in plastic containers .
