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
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
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!!
