Supplies

Wodden popsicle sticks

Rubber band

Bottle cap or any cap a holder for the projectile

Step 1: Create the Fulcrum

Take 4 to 5 wooden sticks and pace them on top of each other
And tighten them with rubber bands at the end.
You can add more or take some away later

Step 2: Attachment of Wedge

Take 2 sticks and band them at one to form a wedge.a wedge is created near the fulcrum which can also change the length of catapult depending on the fulcrum position

Step 3: Secure the Wedge in Place

Use two rubber bands to make a 'x' around the fulcrum.it can be kept loose if change of the length is needed

Step 4: Attach the Bottle Cap

It can be anything which is light and able to carry the projectile and also eject it to a favourable distance.
Load it up,pull back,and fire away.
Try to project the object by also changing the length of fulcrum.
Have fun,keep innovating!!
