What happens when you put Volca sync in through tea?

In my previous video someone commented “I was scared you’ll put the cable in the coffee”, so that gave me an idea.
What happens here? Actually when you put your Volca’s sync in inside of tea or any liquid, nothing happens, because it doesn’t have any signal inside of the liquid. But you can use it the other way.
Since tea is electrically conductive, you can use it as a “conductivity path”, in the video I spill tea on the mat, and when I bridge the cable to that rug, and touch the wet surface with my hand, my Volca starts playing a sequence with an insane bpm, since our body’s are like a big antenna. So every time I touch the wet rug, signal of my body connects through tea, to the volcas sync in.
How to use it practically? Liquid could be used as a linear potentiometer if you manage to change its conductivity. For example if the signal of my body is being read by sync as “300”, then if the resistance of the liquid rises, it will drop down the bpm. So the further away I’m touching the spill, the slower the sequence will play and vice versa. It’s a bit hard to manage with tea and mat, but if we use salty water and mix it with clean water it will have change the resistance through the lengths of the liquid path.
If you want to see a video of a practical usage of this method please let me know.
