2005 Award
KNEX Big Air Ball Tower
( KNEX $99.99 Score: ) The wow-wee set of the season, this ball run is over five feet tall when completed (which will require some adult assistance). Comes with more than 1350 pieces, so not for the meek builders! Four D batteries power the fan that propels the plastic balls through a maze of tubing, and traditional Knex pieces! A fun parent–child project for those who love to build.
