This project will play a different musical note when the green rectangle sprite touches different colors. It uses video sensing. Try holding up colored paper to see what happens. I created a spinning top out of a plastic food container lid and some colored paper. You can make your own instrument from random objects and materials around your house. Click see inside and change the colors to match objects around your home. Click the color swatch in the "touching color" block, and use the eye dropper to pick colors from your own craft project or objects from around your home.
