Showing a Collision

So I have my game running pretty well at the moment, minimal leaks just in a testing phase right now.  My one issue is that collision between objects is so fast that it’s hard to actually see the collision and a player might think the game is cheating them. 

My question is this, is there a way to pause and show the collision on screen before moving onto the score/restart phase of the game?  

Obviously this is a pretty general question but any suggestions on a fairly easy way to implement something would be appreciated.  I’m using storyboard if that helps at all.

maybe you could put a collision event listener on an object and use physics.pause()?
