Introduction: Weight Powered Car
Have fun making this weight powered car.
Supplies
You will need:
A sheet of cardboard
Pen
Ruler
Box cuter knife
Cutter/scissors (for cutting skewer sticks)
String
Sticky tape
2x popsicle sticks
3x skewer sticks
Step 1: Making the Base
Cut a 22cm by 12 cm rectangle from the cardboard
Then cut a rectangle 4cm up and 6cm across at one end.
As shone above
Then cut a rectangle 4cm up and 6cm across at one end.
As shone above
Step 2: Attaching the Wheels
Cut 4 10cm cardboard wheels and mark the centre in each one
Then push a skewer stick through one of the wheels and then push the other side through the base and attach the other wheel as shown.
Glue both wheels using a hot glue gun.
Now do the same to attach the wheels on the other side of the base
As shown above
Then push a skewer stick through one of the wheels and then push the other side through the base and attach the other wheel as shown.
Glue both wheels using a hot glue gun.
Now do the same to attach the wheels on the other side of the base
As shown above
Step 3: Making the Weight Supporter
Cut a 50cm by 12cm cardboard and score two lines down the middle as shown.
Then fold the cardboard and tape the sides .
Then glue the supporter to the car.
As shown above
Then fold the cardboard and tape the sides .
Then glue the supporter to the car.
As shown above
Step 4: Making the Skewer Wider
Cut a 3cm by 10 cm cardboard and glue one end of it to the skewer stick
Then start wrapping it around the skewer stick
(This will make it easier for the weight to turn the skewer stick)
As shown in pictures
Then start wrapping it around the skewer stick
(This will make it easier for the weight to turn the skewer stick)
As shown in pictures
Step 5: Making the Pulley
Cut a 2cm by 6cm cardboard and tape the ends together to make a tube shape
Then cut 2x 3cm circles and mark the centre one both circles .
Now glue the circles to both ends of the tube.
As shown above
Then cut 2x 3cm circles and mark the centre one both circles .
Now glue the circles to both ends of the tube.
As shown above
Step 6: Attaching the Pulley
cut 2x 10cm by 3cm cardboards and glue them to the top of the weight supporter as shown.
Then push a skewer stick through one of them .
Now push the skewer stick through the pulley and push the rest of the skewer stick through the other cardboard
Using a cutter cut off the excess skewer stick from both sides.
As shown above
Then push a skewer stick through one of them .
Now push the skewer stick through the pulley and push the rest of the skewer stick through the other cardboard
Using a cutter cut off the excess skewer stick from both sides.
As shown above
Step 7: Attaching the Weight
Cut a 120 cm piece of string and tie a weight to one side . (I used a bolt)
Take the other end of the string and start wrapping it around the skewer stick
Then lift the weight and put it over the pulley .
As shown above
Take the other end of the string and start wrapping it around the skewer stick
Then lift the weight and put it over the pulley .
As shown above
Step 8: Finishing Off
To strengthen the wheels cut 4x 3cm by 3 cm cardboard pieces
Glue them onto the wheels for extra support as shown (Cut off excess skewer sticks)
Glue two popsicle sticks to the base for extra support
As shown above
And there you have it your own weight powered car
