Just touch VK, mentally make your request and enjoy the party. VK will do his work.
Let’s say you want to send Flab Down Serum to the food you are eating in the party, make a mental connection/talk with VK about the Flab Down Serum 3 times.
You are free to enjoy the party.
Same is when you are in a public place, driving, cooing, washing or doing any other activity where your hands are not Free for rotations.
