Elastic band

Hi,

I am currently making a new game for mobile, and i have already ran in a problem.

I have been trying to make an elastic band wich I can pull by swipping down and releasing it would then throw the ball(wich is attached on begin play), so I was wondering where to start with this.

bear in mind I have already implemented the swiping mechanism in the level blueprint wich works, but i dont see how I could make it that swipping down bends the elastic(cable component) nor can i get acces to the swipping as it is in level blueprint.

Picture attached.

many thanks,
Sam.
