Instructions

First cut off the top of a white Pediasure plastic bottle.

Make two holes on each side of the top third of the bottle and two holes on the sides on the bottom third of the bottle.

Cut two 19″ thick rubber band pieces, one will go throughout the arms and the other will go through the lets of your robot.

Insert one rubber band piece throughout the two upper holes in the white plastic bottle and the other piece through the bottom holes.

Cut off the bottoms off of two orange juice bottles. Make a small hole in the center of one and but the cable with the led lights through the hole leaving the battery pack on the outside.

Wrap the LED lights around the white plastic bottle.

Bring the two bottoms of the clear plastic bottles together around the white bottle with the LED lights, these will be the chest and the back of your robot. Make sure the battery pack is in the back.

Make two small holes on each side of the chest piece and two small holes on each side of the back piece and tie the chest and back together with two plastic ties. You should have both rubber band pieces sticking out on the sides and on the bottom of your robot’s torso, these will make the arms and legs.p

Make a hole on the bottom of 4 Pediasure bottles and on opposite sides of 4 ping pong balls.

Remove the metal top off the 4 plastic caps (from the Pediasure bottles), this will leave only a ring with a large round hole in the center of each cap.
