How do I make a transformers costume?

I want a transformers costume that actually transforms but I don't want to spend too much money, does anyone have some instructions?|||Tak a larger box for the body, a smaller box for the head, and some paper plates or pie tins for wheels and lights, and some paint.


First, cut the bottom flaps off of a big cardboard box. Cut holes for your head and arms. You'll need an adult to help you with this part.





Cut off the flaps of the small box so one side is open. Then cut a large hole in any other side of the box except the top.


Tape the small box on top of the larger box so the hole in the box is in front. The small box will be your robot's head.





Decorate the body any way you want.
