Suspension Bridge and others

He also made these you can see closer, by himself, a fan and another swing ride, sailboat and glider.

My six year old created these by himself. I'm especially proud of the long suspension bridge, completely original/by no instructions. The lower photo is an attempt of building a bridge, still pretty cool.

Knex Airplane Ride, Submarine
