This one turned out more interesting then I originally thought! I had recorded this with how I used to do it in the past, showed it to someone at work and then he showed me another even cooler way to do it. So I re-recorded the video to include both techniques.
Shoutout to Arjan from House of secrets who showed me the COPs technique
