"Hogwarts would be proud to accept such a donation, Mr. Potter. I thank you on behalf of all the staff for your generosity." Dumbledore smiled kindly as Harry nodded while doing everything he could to keep the red from his cheeks. Turning back towards the students Harry motioned for Tonks and Penny to come up and then picked out six more students. When all eight students stood up front with him there were two Ravenclaws, two Hufflepuffs, two Slytherins and two Gryffindors. Neither pair was from the same year so that students would be able to see the range difference that was possible between people even if they were only a couple years apart in age.
"Tonks, would you do the honors? Show everyone how it works." Harry asked as he handed her the Test Frame.
"Gotcha, Harry!" Tonks grinned as she directed her mana into the frame. When her number appeared she grinned before turning the frame around to show the students. The glowing '4812' was easily visible to everyone in the hall. Tonks handed the Test Frame over to Penny who quickly got her own reading. The Prefect smiled happily at her number before showing it to the hall, it read '3006'. The next student accepted the frame from Penny he was a Gryffindor in his sixth year if Harry had to guess. It only took a moment of trying before the teen got the frame to work and showed his reading to the hall as well, a glowing '3456'. The next student was Emilia Hawthorn herself. She poured her mana into the frame and watched as the numbers climbed. When they stopped she gave a small grin before showing the hall the '3628' inside the frame. Emilia handed the frame over to the younger Slytherin beside her. The boy was only a second year and got a reading of '412' which he showed to the hall.
"This is so cool!" Exclaimed the Gryffindor boy that got the frame next, he was practically vibrating in excitement. Harry thought he was probably a second year too. A glowing '384' was showed to the hall before he passed it over to the Ravenclaw girl that stood next to Penny. The girl in question was a fourth year by the name of Elise Spindle. With a smile of her own she activated the frame and showed everyone her '964'. The last person to hold the frame was a Hufflepuff called Cedric Diggory. The teen smiled as he poured his mana into the frame and happily showed his reading to everyone, he'd clocked in at a rather impressive '1154'. Before handing it back to Harry Cedric gave his thanks for being chosen to demonstrate.
"As you can see Magical strength varies greatly between individuals. How much you practice will affect your growth and age often leads to higher numbers." Harry explained as he held the Test Frame.
"How much do you have?" called one of the Weasley Twins before Percy could stop him.
"Hmm, it's been a little while since I checked, but I practice a lot in my free time so I think I'm a bit higher than normal." Harry shrugged as he poured his mana into the frame. Looking down at it for a moment Harry turned it around and showed the glowing '406'. "Anyway, now that you all know how it works I'll leave the Test Frame on the Head Table in front of the Headmaster. Just form a line and you can measure your mana today."
"I'll make sure the frame gets back to you Harry." Dumbledore smiled getting a nod of thanks from Harry. There was already a line of every student forming behind him and Harry quickly moved out of the way so that the readings could begin. He quickly made his way out of the Great Hall and was followed by Tonks and Penny.
"You did great, Harrikins!" Tonks smiled as she ruffled his hair. Harry groaned as he pulled away from her and tried to fix the even worse mess his hair had been made into.
"I believe you did well too, Harry. You've gotten a lot of interest in your product and that'll make them easier to sell when you're ready." Penny congratulated him as he made his way towards his hidden workshop.
"Thanks you two, but after standing in front of the whole school I'm a bit out of sorts. I'm just going to be in my quiet workshop making those four new Test Frames for the school." Harry stated as they walked through the corridors.
"What he means is that he's going to hide from everyone until he calms down." Tonks laughed making Harry grumble that he wasn't hiding.
"Tonks be nice, that was a situation a lot of people would be nervous in." Penny admonished as they made their way into Harry's workshop.
"I know what I said!" Tonks laughed as she hugged Harry from behind.
"Tonks!" Harry cried out as he flushed dark red.
The next day Harry received six letters from various Magical Scholars, Enchanters, and one from a company that sold Enchanted Objects. Not overly eager to have everyone in the Great Hall trying to read his mail over his shoulder, Harry stuffed the letters into his robe pocket and finished his breakfast. After classes Harry was on his way up to the Ravenclaw Tower when the moving stairs shifted and brought him to the right hand corridor on the third floor.
