Amazing Rubber Band Cars: Easy-to-Build Wind-Up Racers, Models, and Toys
The Basic Rubber Band Car In this chapter you will learn will learn how to build a basic cardboard car powered by rubber bands Materials and Tools 1 8 inch thick corrugated cardboard Scissors Pushpin 2 round pencils White glue 2 rubber bands D cell battery Time to get started Copy the templates from pages 11 and 12 onto cardboard You will need one
