DIY Capacitive Senor

I’m relatively new to electronics and Arduino for that matter.
after fumbling around trying to solder to aluminum foil…
I realized that a mechanical means of attachment might work
a little better.

I rolled a 1k ohm resistor to one side of the foil (as a receive)
and a 1M ohm resistor in the other side (as a send). I then
twisted the aluminum foil and the resistor wires into a bundle.

I attached a picture to clarify what I meant. initial format was large
so I had to compress it hence the PDF

  1. Is attaching them in this manner an awful idea?
  2. Will this still work for my purpose?

this is the link I got the idea from.
