How do you make a self propelled cars using household items and newtons laws?

Answer 1

well.... i dont really know how either.... but i have to figure the same thing for a project of mine... but i have been researching on it for a few minutes now on google.... most of the sites that i visited talk about using rubber bands to help propell the car.... u could also use a water bottle or soda bottle... but the bottles have to have pressure in them... so when u take off the cap, the pressure being released would make the car move forward. i know that thats not much but i hope that gave u some ideas. good luck.
