Supplies
You will need:
A sheet of Corrugated cardboard
Hot glue gun
Pen
Ruler
Rubber band
Tape
Skewer stick
Box cutter knife
Making the Base
Cut two pieces of cardboard
Cut one of them 15 x 9 cm and the other 14 x 9 cm
Take the 14 x 9 cm cardboard and score a line through the middle and fold it
now take the 15 x 9 cm cardboard and glue the 14 x 9 cm cardboard onto it using a hot glue gun
as shown above
Making the Arm
Cut a 19 x 9 cm rectangle from the cardboard
then score two lines 3 cm apart all the way down
Then take some tape and tape it together to make the arm
As shown above
Attaching the Arm to the Base
Cut a piece of cardboard 6 cm x 3 cm
Score a line through the middle
This will be your pivot point
Then glue the pivot point onto the arm about 3cm down as shown
Now take the arm and glue it onto the base as shown
Making the Basket
Cut a square piece of card board 5cm x 4cm
Then score a line 1/2cm on all four sides then turn it around and fold them upwards as shown in the picture to create your basket.
(You can glue the sides together to make it s stronger)
Attaching the Skewer Sticks
Cut a skewer stick 3 cm long and glue the middle of it to the underneath of the launcher as shown (don’t glue the sides just the middle as this is where your rubber band will attach later)
Then cut 2 x 4cm pieces from the skewer stick and push 1 piece through the top of the arm and glue the second piece onto the back of the arm as shown in the picture
Attaching the Basket
Take your launcher and glue the basket onto the back of it
This will be the area you put an object to lunch it
Attaching the Rubber Band
take your rubber band and attach it to the underneath of your launcher as shown
Then take the rubber band and stretch it over and around the top skewer of the launcher
As shown above
And there you have it your own rubber band powered launcher.
