Arjuna uses projection

An idea comes to you. Without explaining you quickly pat your dad down for a spare pen-making sure to tickle him in the process, of course-and then guide yourself into a meditative trance. Once your mind returns to that floaty void of ideas and energy, you begin to scan the pen purely on a physical scale. So much of your focus is dedicated to the task that you easily move down to microscopic, past single-cellular, deeper than molecular, and only begin to have your sight blur once you can sense the individual electrons whizzing-and popping? And weird other things too-around their respective atoms. The conscious mind can't truly memorize such an impossibly dense amount of information, but the conscious mind doesn't have to. One hand serves to gather the data, and in the other hand a glowing wire-frame forms.

It takes several long minutes, not because of the difficulty of the procedure but because the process is being ingrained into your instincts. And then all at once it's done. Your eyes snap open, impossibly transferring from meditative to wakeful in a mere moment, and you gasp upon seeing a perfect replica of dad's pen sitting in your other hand. You also laugh a bit sheepishly upon seeing dad's annoyed and vaguely displeased face.

After explaining to dad what it is you were trying to do and exactly why there was no danger involved whatsoever and that you were just afraid of losing your inspiration, promise!, he finally relents and you avoid getting grounded. After that, though, comes The Waiting. Your Projected pen displays the exact same physical properties as dad's pen, and can even write with what seems like real ink. It's just as tough as dad's pen too, and breaking part of it doesn't cause it to turn into bits of light like your empty Projections. What it does do is...fall apart. It's like watching the pen sort-of-but-not-really age in fast-motion; the longer it exists the faster bits of it crack and pieces of it chip away. It never rusts or loses its luster, but over the course of the next few hours it simply falls apart until nothing really remains of it.

Recreating the pen is the work of a few seconds for you, but creating something you've never scanned before for the first time is the work of a few minutes. On the other hand, they're all effectively real items until they start disintegrating, which means you now have an infinite supply of tasty and calorie-free candy. You're pretty sure this means you've become the uncontested god of the playground.
