Where or how did Charles Lindbergh go to the bathroom on his first non stop flight across the Atlantic?

During his historic non-stop flight across the Atlantic in 1927, Charles Lindbergh used a makeshift solution for bathroom needs. He had a funnel connected to a tube that allowed him to relieve himself while sitting in the cockpit. This rudimentary system was necessary due to the long duration of the flight and the confined space of the aircraft, the Spirit of St. Louis. Lindbergh's ingenuity in managing such practical needs was part of the overall challenge of the pioneering flight.
