Girl Scout Powder Puff Derby Rules

Car Structure

Cars must be made of wood, and Girl Scouts must make the cars themselves. The Official Pinewood Derby Kit provides Scouts with the materials they need to make the car, and girls must manufacture the cars using this kit. Pre-made cars and cars used in previous Powder Puff or Pinewood Derby events are not allowed. Car wheels should not contain springs.

Car Size

The Official Pinewood Derby Kit allows cars to have a wheel base of 4 1/4 inches, and girls cannot alter their cars to shorten or lengthen this distance. Cars should be no longer than 7 inches and no taller than 5 1/2 inches. Cars must weigh no more than 5 ounces and should be structured so all four wheels touch the track at all times.

Race Rules

The cars compete down a 32-foot-long track that's 5 feet high at its tallest point. The last several inches of the track are leveled off, and judges determine the winner of each individual race. Winners then compete against one another to determine the champion of the final race.

Miscellaneous Rules

The Powder Puff Derby teaches girls the importance of fair play and friendly competition. Thus any kind of cheating will immediately disqualify girls from the race. Bullying, name-calling and teasing are also not allowed. Participants can appeal the rulings of race judges if they feel the decision is unfair, but fighting or arguing with the judges is not permitted.

How to Make a Wind-Powered Car

Design the base of the car. Draw the base on the cardboard. You can make it any size or shape that you'd like, but make it at least 4-inches by 6-inches.

Trace the base of your glass on the cardboard four times. Make sure these are traced smoothly, as they will become the wheels.

Cut out the pieces of cardboard. Make the cuts as smooth as possible.

Turn the base upside down and draw a pair of parallel lines on it. These lines will be where the axles go, so make them perpendicular to the sides, and put one in the front and one in the back.

Glue the straws to the bottom of the vehicle. Trim off any excess straw.

Pierce the exact center of one of the wheels with one of the skewers. Glue the skewer in place at the end of one of the wheels. Repeat with the other skewer and another wheel.

Slide both skewers into the straws at the bottom of the car base.

Pierce the center of the other two wheels with the exposed ends of the skewers. Glue them into place, but be careful not to glue the straw to the skewer. Slide the wheel close to the car, so you can trim off any excess axle.

Pierce the middle of the car base with a skewer and glue it into place poking upward. The bottom of this skewer should more than clear the floor.

Design and draw a sail on the construction paper. A larger sail will catch more wind, but you can make it any shape that you want. Mark the point at the top and bottom of the sail where it will attach to the mast.

Slide the sail into place on the mast. Pierce the marks and make it curve forward. If the sail starts to slip, tape it in place.

Things You Will Need

  • Cardboard
  • Marker
  • Empty glass
  • Scissors
  • 2 straight straws
  • Glue
  • Tape
  • 3 skewers
  • Construction or printer paper
  • Markers, colored pencils, or crayons
  • Masking tape
  • Floor fan


If the car base bows when the sail is attached, use a few skewers to reinforce the middle of the car.

How to Build Mini Racing Cars

Draw three 1-inch by 2-1/2-inch rectangles on a piece of cardboard.

Streamlined surface, curved corners, and a sleek look. You can make your car look however you want.
Streamlined surface, curved corners, and a sleek look. You can make your car look however you want.

Draw the top of the car on one of these rectangles. You can add rounded corners or other features on this. Draw a wheelbase onto the second rectangle that looks similar to the upper first rectangle. Make the remaining rectangle into the middle layer of the car, copying any curves or changes in shape between the other two pieces.

Cut the layers of the car out of the cardboard.

Place glue on the bottom layer of the car, then glue the middle layer in. Repeat with the top layer of the car onto the middle. Leave the glue to dry for a few minutes.

Cut two pieces of straw to 1-inch lengths.

Glue and tape the straws to the underside of the car. Place them 1/4-inch from the front and back of the vehicle.

Cut the dowel to two 1-1/2-inch lengths.

Stick the dowel through the toy wheels. Glue the wheel in place. Repeat with the other dowel and another wheel. Leave the glue to dry for a few minutes.

Slide the dowels through the straws.

Glue the remaining wheels onto the exposed ends of the axles. Make sure the glue doesn't get on the straws, or they may get stuck.

Decorate the car, painting it any color you want. Draw on features like headlights, a windshield, or doors. Leave the vehicle to dry for a couple of hours before playing with it.

Things You Will Need

  • Cardboard box or Styrofoam meat tray
  • Marker or pencil
  • Scissors
  • 8-inch drinking straws
  • 8-inch wooden dowels or skewers
  • 4 wooden, plastic or toy wheels, bottle caps or anything that can act as a wheel
  • Glue or masking tape
  • Paint
  • Construction paper
  • Glue stick (optional)


Make a ramp out of a plywood plank and rest the vehicles at the top. Let two vehicles go at the same time to race them against each other.

How to build a self propelled toy car

Fold the art foam in half width-wise. Draw a rounded rectangle covering most of the half sheet and incorporating the fold.

Draw a 2-inch half circle at the fold, 1/3 inch from the fold edge.

Draw 1/2-inch squares near the bottom rounded rectangle corners.

Cut out the rounded rectangle, the half circle and the squares with the mat knife while the art foam is folded.

Pinch together the inside edges of the rectangle at the opposite end from the half circle and add a glue dot to secure it.

Draw two 2-inch diameter circles with the compass. Draw two 1 3/4-inch diameter circles with the compass.

Cut out the circles and paint them black with silver centre circles for wheels.

Cut two sections of straw to measure 3 inches each. Thread them through the small squares on the bottom of the car for axles.

Glue the wheels to the ends of the straws, placing the smaller wheels at the front of the car.

Tape the balloon on the end of straw. Thread the straw under the body of the car, above the axels with the balloon at the front of the car.

Blow up the balloon through the straw, put the car on a flat surface and watch it take off.

How to donate child car seats

Check your car seat against the list of recalled car seats. If it has been recalled, you should not donate it.

Call your local Department of Social Services to ask if they accept car seats donations. If they will, you can take it to them and request a donation receipt to use for a tax deduction.

Call homeless shelters and shelters for women to ask if they can accept a car seat donation. If they can, make an appointment to drop it off, requesting a donation receipt.

Call local hospital and medical centres. They may offer programs helping low-income mothers prepare for having a child. They should also be able to give you a donation receipt.

Clean the car seat without disassembling it or putting the harness straps in the washing machine.


If no organisations will accept your car seat, and it hasn't been recalled, you can drop it off with any Goodwill, Salvation Army, or YMCA store.

How to Make a Fan Car

Cut a flat panel car chassis from lightweight and rigid materials like plastic or wood. A basic rectangle shape wide enough for the base of the fan is all that is necessary. The width of the chassis must be narrower than the length of the axles.

Drill through the chassis crosswise 2 inches from the front and 2 inches from the back. Make holes that are only slightly wider than the axles. Thread the axles through the hole at the front and rear of the chassis.

Attach the wheels to both ends of the axles. Test the wheels and chassis to make sure it rolls. Make adjustments to the shape of the chassis or position of the wheels until the chassis rolls smoothly on a flat surface.

Place the base of the battery-powered fan on the chassis just above the rear axle. Use adhesive tape to thoroughly secure the base of the fan to the chassis. Load batteries into the fan.

Turn the fan onto its highest power setting. Place the fan car on a flat even surface. Monitor the way the car travels so adjustments and improvements can be made.

Reduce the overall weight of the chassis by cutting away unnecessary material if it too heavy for the fan to push. Add counterbalance weight to the area above the front axle if the front wheels are popping up. Switch in a more powerful fan to increase travel speeds.

Things You Will Need

  • Chassis material (plastic, cardboard or wood)
  • Drill and bits
  • 2 axle and wheel sets
  • Batteries
  • Adhesive tape
  • Lubricant


Lubricate wheels and axles on fan cars to reduce friction. A small amount of oil on the venter of the fan blades can help them spin more freely and push the car faster.


Fan cars are a bit unpredictable. Test and race fan cars in a large open space where it has plenty of room to roam.

How to Make Balloon Buggies

Design the frame of your buggy. An ideal buggy should be 6 to 8 inches long and 4 to 6 inches wide at its widest section. Lightweight materials like styrofoam and cardboard work best. Your frame should be triangular or rectangular in shape. Styrofoam works better as a rectangle. Cardboard cuts easily into a rectangle, or you can create a "V" shaped body. You can add additional pieces of cardboard to the "V" or triangle shape so that the axles will have something to attach to. If your car is made up of several pieces, use hot glue to secure them together.

Create wheels for the buggy. Buttons and bottle caps are options, although you can get creative and use almost any circular object. If you are using bottle caps or other circular objects without holes in them, use a small hole punch or similar object to make holes.

Construct two axles for your car. Your axles can be made from bamboo skewers or sewing pins. Pins work with styrofoam, as they can be inserted directly into the buggy base. You can also push bamboo skewers directly into styrofoam. An alternative method is to use hot glue or tape to add straws to your car base. The straws act as a bearing so that your axle will turn. Thread the bamboo through the straws once you have secured them. If necessary, trim the bamboo to the desired length. Make sure the axles spin fluidly.

Attach the wheels to the axels. You can keep them in place with hot glue if necessary. Let all of the glue dry completely, and then test your buggy to see if it rolls. Make any necessary adjustments if the wheels are not moving properly.

Partially blow up a latex balloon. The balloon should not be bigger than the body of your buggy. Attach double-stick tape to one side of the balloon. Without letting the air out, press the balloon onto the frame of your car. You can also insert straw into the balloon so that you can blow it up again while it is still attached to your balloon buggy. Let the balloon go and watch the car take off.


This project works best with children over the age of 7.


Adult supervision is required when working with hot glue and scissors.

Directions to Transform a Bumblebee Transformer

Transformers the Movie Bumblebee

Transforming Bumblebee to robot mode starts with opening the driver and passenger doors. Once you open the doors the roof will separate exposing the interior of the vehicle. This will also help free up his other components to assist in his transformation. The middle will allow the top and bottom to pivot so you can pull the legs down. The feet will unfold from the rear of the car. At this point pull the arms out from under the hood and bend the hood down to expose the head. You can adjust the doors to protrude out like wings. Follow these instructions in reverse to transform him back to his Camaro form.

Transformers Animated Bumblebee

Flip out the top rear panels. They have rocket launchers attached. Once the panels are lifted up you are ready to transform the torso. Flip the front of the vehicle, separating it from the bottom of the vehicle. This piece will flip all the way toward the back of the vehicle. The very end will turn over to form the feet. The front wheels will pull out to form the arms. Bumblebee is ready to stand up while you make adjustments to the back by pulling them closer in to the head and bending them behind the body out of sight. Bumblebee is now ready for action. Follow these steps in reverse to transform to alternate mode

Transformers Generation One Bumblebee

Start by sliding the back of the car away from the front. Twist the arms out from the side of the cars. The head will flip out from the back of the car. Bumblebee will be ready to stand up.
