To make this mechanism you have to fold the paper in half and make two cuts along the folded edge. Then, leave that piece of paper and get another piece. Cut a strip of paper and attach what you want to slide (a rocket). Finally slot the strip through the cuts in the first piece of paper. Voila! you have a sliding mechanism.
First you get a piece of paper and draw your picture. You need to decide which part will be a flap and what will be behind it. Then get another piece of paper and draw the flap. Stick it onto the page and fold it at the edge. Voila a flap!

Get a folded piece of paper and make 2 slits in the fold. This will then form a step when you open it out. Get another piece of paper and cut out picture you want to glue onto the step. Voila! A step.
