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.
