Wanna make some? Here's what we did:
Next, I looked at the airplanes I found on Probably Actually, and hand drew on another piece of cardboard all of the pieces that I would need. I cut them all out, put together the tail piece, and added foil baking containers to the front of the bigger boxes to give them some dimension. :) Then, I laid all of the pieces out on an old tarp in the garage to be painted! It isn't in the picture, but don't forget the circle for the propeller as well.
After they were done being painted, I just put all of the pieces together with packing tape.
For the wings, I attached tape to the bottom side first, so that it would have a little bit of hold. Then, I lifted the wings up to an upward 45-degree angle. (Would that be a 135-degree angle? Geometry was a long time ago...) I taped them tightly, so that when I let go the wings held perfectly at a 90-degree angle. If you try to just tape it at 90-degrees, it will fall when you let go. Do the same thing for the tail piece.
For the propeller, I hot glued and taped it on. The foil baking containers made it a little bit harder to keep the propellers held on. So, you may want to just skip that part!
And, you are done! You should have something like this...
Not to mention, we got some really cute pictures!
