Sam held his hand up and began channeling his focus. Sparks of green light began to appear over his palm, turning into small squares and rectangles before forming a number of strange symbols.

"These are what we call Runes." He said. "I'm still in the process of studying them but… you could say they're something akin to a programing language."

"A… programing language?" One of the men raised an eyebrow. "You mean like in a computer?"

"Something like that. Using these runes one can create several phenomena that technically shouldn't be possible, like becoming weightless and flying around with no kind of special equipment, for example."

Sam released his focus and allowed the Runes to disappear. The parents who were staring at them with great interest snapped back to reality, but they were still at loss for words.
