And with that, the last of the locks fell to the bottom of the tank, followed by the chains, and then Ian's feet. Huzzah! He was free!

He quickly pushed to the surface of the tank and stood up, taking in a breath of fresh air. "You were all fantastic!" he exclaimed. "I knew you all would save me!"

He didn't dare tell them he had cast that bubble-head charm. "Thank you all for your assistance, and of course thanks to you as well, Mr. Masterson." He nodded and winked at his nephew and turned back to the class.

"Well, that will be all for today, class. For your homework, I would like you to simply practice the charm with the locks over there by the window. Please take one each and go around the school, finding something to place the lock on. Then, all you have to do is unlock it!

If you have any questions about today's lesson, feel free to ask me after or come by my office. Other than that, you are free to go after you have picked up your lock! Have a wonderful day, everyone!"
