@jess22 If you draw wires from batteries/converters to the light bulb trees, they will destroy the ink blobs!
Also, the converters change the color of the wires you're drawing. So say you have a red battery, a red and yellow converter and a yellow socket on a machine, you can draw from the battery to the red side of the converter, press done, then draw a wire from the yellow side of the converter to the yellow socket.
