Go play with Trilia's balls

The four of you exit your room. The common room was emptying out a bit as most girls either filtered into their own rooms or had gone back out to the campus. You were in good spirits. Your fears of not being able to relate to other people were far too pessimistic. In fact between the boys yesterday and these girls today you had probably made more friends as a girl than your entire life as Jacub. The four of you exit the building, once again feeling the dispelling tingle. It's now well into the afternoon as you approach the park and it's bustling with activity. Groups are mostly sex segregated, especially among the younger looking groups, but the older students are more mixed.

The four of you find a flat patch of grass and Trilia hands you a familiar leather ball.

Trilia : "Ok, so my parents said the trick is to imagine that the ball is in your hand, even when it's not and they're charmed to react to your intentions"

You're not quite sure what she says wasn't total gibberish but you try to understand.

Trilia : "To start out place the ball a short distance away from you and mime picking it up as if it were actually right in front of you"

She put her own leathery ball on the soft turf and took a step back. before looking at the ball and miming picking it up with a concentrated look on her face. She looked insane and you barely suppressed a giggle, at least until the third time she tried to reach down and pick up an invisible ball before her feet and the actual ball reacted exactly in time to her movements.

Amber : "Wow, you actually did it. I had heard it usually takes a whole day of trying to get it to work on your first go."

Trilia : "Guess I just got lucky."

Trilia is looking really impressed with herself but manages to not come off too smugly, just excited to be good at something. With her success the rest of you set out trying to achieve the same results with your own balls. Amber is the next to succeed after 20 more minutes of trying, during which Trilia has progressed to remotely tossing the ball up and letting it fall back down to the ground, trying but not succeeding at catching it mid air.

A group of three boys who appear to be upper classmen walk up to the four of you while you continue, now a little frustratedly, to try and pick up the ball.
