Step 8: Test the Paperweight
Before proceeding to the last step, this is a great time to test the paperweight and see the fruits of your labor. Connect the 9 volt battery to the battery clip and you should see the LEDs illuminate and start cycling through the colors as shown below. Because the LEDs don't change color at exactly the same time and because they are wired in parallel and draw current at different rates, the LEDs will get out of sync and you'll see different colors at the same time and some may flicker and vary in brightness. Pretty cool!
