This guide is for building an iPhone stand for parents to use on an airplane to hold the phone on the tray table. It is made from kid k'nex, which some kids have. It secures the phone in a good viewing position on the tray table of the airplane and can even be used on a center console of a rental car by just tying it down using a string or ribbon. When you are not on the plane or if the kids get bored of the iPhone, bring a couple more parts and they can take it apart and build with the k'nex.
Step 1: Collect the parts
The kid k'nex I used came from the ZOOMIN' BUDDIES set. You can see the instruction book in the picture. This set had all the pieces I used. You can probably find the pieces in other similar sets. The pictures of the pieces are in the next step.
Step 2: Detailed Picture of Parts
The parts consist of 2, 135° blue angle pieces. 2 blue short connectors, 3/4" or so long. 4 yellow joint pieces that can bend. And 2, 2 1/2" yellow pieces.
Step 3: Putting it together
The yellow long pieces will be placed into the second and fourth slots on the blue pieces. You will have to slide these into place side ways which is not typically how they fit together but they will fit. Then you will put the blue short connectors in between the yellow long pieces. On top of the blue connectors you'll put two of the yellow bendable joint pieces. The last 2 bendable joint pieces will go into the remaining 2 slots of the blue angle pieces. See the picture below.
Step 4: Inserting the iPhone
The last step after getting everything put together is to insert your iPhone or iPod touch. You'll be able to bend the bendable links to hold the phone in position so it won't move around or slide out. Add a splitter and 2 headsets and my boys were fine on a 3 1/2 hour cross country plane ride.
