This was ridiculous. The blue demon was asking them to lightning bend with their tongues. Zuko scoffed and stayed back as the other students started doing the test. When he saw the light bulbs lighting up however, he got confused.

No one in this world knew how to bend fire or even feel energy and now they were making electricty. With. Their. Tongues. This was crazy. And more than a little bit interesting.

Zuko stepped forward and grasped the wires. He frowned down at them, but he couldn't feel any energy from them. He looked fervently around before opening his mouth and... touching the wires to his tongue. His eyes widened as the light bulb started working. He quickly pulled the wires away and the light went out again.

"This isn't possible."
