The coolest car to play with is the one you make!

Whether we’re jumping on a bike, boat or toboggan — or maybe pushing a truck around a sandbox — making things go makes for timeless and exciting fun. This DIY propeller car project is the perfect activity for the budding engineer at home — a kid who’s looking for a little more power than pushing their toy car around by hand. Using some easy-to-find petroleum products — plastic straws, a food container, glue and some simple electronics — we can build an assembly line and make a propeller-fueled car.

Propeller Car

Here’s what you’ll need:

  • AAA batteries
  • DC motor
  • Dowels
  • Hot glue gun
  • Glue stick
  • On/Off switch
  • Plastic bottle caps
  • Plastic container
  • Propeller
  • Scissors
  • Straws

Here’s what to do:

  • Create the axles by carefully attaching the straws to the bottom of the plastic container using the hot glue gun.
  • Build the wheels by gluing a plastic bottle cap to one end of a dowel. Once dry, slide the dowel through the straw and glue another bottle cap to the other side. Do this for each axle.
  • Connect the switch and battery pack to the motor using your hands or pliers. Place batteries into the pack.
  • Glue the battery pack and motor onto the top of the container.
  • Attach the propeller.
  • Flick the switch and let go!
