Steps:
            1.   Mark the center of two popsicle sticks. Glue them together with hot
               glue to form a "+" shaped frame.










                                             2.   Cut four pieces of straw, 2–3 cm long. Glue the pieces to the ends of each
                                                 popsicle stick to make legs. The straws are clear, so they are hard to see
                                                 in this photo.








            3.   If needed, cut the connectors off the motor wires. Strip about 1 cm of
               insulation off of each wire.





            4.   Glue the motors to the tips of the popsicle sticks, with the wires hanging down by the straws. The motors
               with red and blue wires should go opposite from each other, and the motors with black and white wires
               should go opposite from each other.




















                                              5.   Cut two pieces of 30 AWG stranded wire, each about 1 m long. Strip
                                                 about 1 cm of insulation off the ends.
                                              6.   Connect all of the red and white motor wires to one of your long pieces
                                                 of wire. This will be the positive connection to the battery pack. Do
                                                 this by twisting the ends of the five wires together, and covering the
                                                 connections with electrical tape. You may need to use additional shorter
                                                 pieces of wire to make all the connections if the motor wires are not long
                                                 enough. In this picture, the red and white motor wires are all connected
                                                 to the long yellow wire.
