Watch this gravity-defying wooden ball and track set from Wonderworld! The Trix Track Power Booster Track Set lets your ball start from bottom and UP to the top, not down! Power booster is going against gravity. When the ball goes through a power boosting station, the hammer hits the ball so it can run up the tracks. Mix power booster with your other Trix Track sets for more fun!
