Note: The engine and ballon retaining band should NOT be adhered to cardstock

  • Cut out engine and ballon retaining band
  • Give a curl to the paper by pulling each piece over the sharp edge of a desk or table top. This will make the paper easier to roll
  • Form the engine by rolling it around a pencil or the handle of your hobby knife. Keep the ends even and roll tightly. Glue last wrap in place, then remove from dowelling
  • Roll the balloon retaining band around one end of the engine, gluging the first and last wrap in place
  • To strengthen and waterproof the engine, saturate the balloon retaining strip with super glue. Use enough glue to wet the paper both inside and out. Be careful not to get super glue on your fingers! Set engine aside to dry completely
  • Mount the engine by gluing it between the engine supports as shown. The balloon retaining band should be toward the front of the car. The engine should extend beyond the supports far enough for the balloon to be attachedÂ
