Keep it Simple

  • Start small with a toy car challenge. Reusing an old egg carton, a few pencils or sticks, some rubber bands and whatever other materials you have on hand, try building a structure that can support the weight of a small car.

Take it Further

  • Don’t stop at a miniature bridge—try making one that can hold the weight of a member of your Patrol! What materials could you use to scale your bridge up to support the weight of a person? Invite an engineer in for advice and ideas!
