To make an eco-police car we need two boxes (one smaller and one bigger). We paint a bigger box with grey poster paint, to a smaller one children sticks pieces of grey paper. Then we glue one box onto another. Two plastic cups will serve as a signal however first we have to stick red and blue crepe to them. We cut out two long stripes and a rhomb for a tailback from blue Bristol board. From white sheet of paper of A4 format we cut out a number 997 and a writing POLICE which we stick on blue elements. We create dipped headlights from match boxes painted in black. Now we have only to cut out four black wheels and four smaller in white colour. We stick circles one onto another. Prepared in this way we stick to paperboard and our car is ready.
