2 cardboard boxes (large enough for a child to sit in), duct tape, an egg carton, a box cutter and scissors.
Here are the pictures. It is pretty easy to put together. ;)
First, I taped the box together with the duct tape and then cut a hole in the top. The smaller kids did have to be lifted and placed in the plane, but they did not mind.
The propeller was simple. You need 2 or 3 blades and a disc shape to tape them to. I also cut strips about 2 inches wide and taped them to the disc to raise the propeller off the plane.
On the inside of the box, I taped half of an egg carton opposite the propeller to use as the control panel.
For the wings on the side and the tail, I just made slots on the box, inserted and taped them in.
There you have it. I think the whole project took about an hour. I'm thinking about making a few other box vehicles for my son's birthday party this spring. Who knows?
