"You can touch them. They aren't charged yet, but they have been. And once charged the polarity will stay the same. And you can always touch them, I've never been shocked, or electrocuted. But not discovering they had polarity or that it stayed the same is why I went almost a whole year without eyebrows." Sarah knew she could make anyone feel tall, at only five foot one, she did note how Lyla moved. A little grin touched her lips. "The explosions never damaged the things the crystals were meant to be protecting, they still did the job, it was just the magic discharging. But once I discovered they had polarity, I realized instead of discharging violently that they could be used like a battery. And I got to keep my eyebrows." It was a long-winded explanation, maybe, but she had gotten a little excited, already, with the discussion about genetics. And she knew the crystals already installed would have a little bit of a charge to them.
