Tire see saw...... made from an old tire, pine wood board, play gym handles and some spray foam to fill in tire.(did not want any snakes getting comfy inside the tire). Painted everything then sprayed some clear enamel spray paint to protect it. Although I don't think I like the foam- it doesn't seem to rock as good as it did without it.
