Morgan said incredulously in his heart: "Hermione, it's already discolored, what should I do next?"

Hermione also couldn't believe it and hurriedly flipped through the book in her hand: "I'll take a look, the book says that it can be turned blue, or the color won't change much, but I didn't expect it to be able to turn pink." ”

"Now let's put this in a crucible and cook it for five minutes, so that the effect of the daffodil grass can be the best and the effect can be the best."

Hermione was still flipping through the book, and Morgan had poured the liquid into the cauldron.

"Morgan, I'm going to start the timer now, and I'm going to take it down in five minutes, not a little more, that will have a deep impact."

"Don't worry, Hermione, this is a high-grade crucible with its own timekeeping, and nothing can go wrong."

Five minutes is a quick time, but it becomes very long during Morgan's observation, observing the changes in it.

Sure enough, after heating, the color became very fast, from pink to pale pink, and then to white.

Morgan then learned that the color can only turn white after heating, so when the cacyira beans are added to it, there will be even more different changes.

"Hermione, it's time for us to put the multi-essence powder inside."

"Of course you can, but you can't add too much, you have to put it in according to the proportion, you can't put it in directly."

"Okay Hermione, the book can be adapted."

After putting things in like this, the water temperature was not too hot, but it was already hot, and the powder of the multi-essence stone turned milky white in an instant.

"According to the book, the finished product is milky white and looks like it has worked, now it's time to find a place to try it."

As he spoke, Morgan looked around, as if he wanted to find a tooth to change color.

Hermione smirked, "Don't look at me, my dad is a dentist and my teeth are white." ”

Morgan gave Hermione a blank look, ran upstairs and got a box down, "This is seal tooth, a substitute for ivory, this has been sitting for a long time, you can try it." ”

Hermione didn't expect Morgan to take out this kind of thing as an experiment, she smiled a little embarrassedly, and then actually took the thing and dipped it in a little milky white liquid and dripped it on the box.

In the next moment, the box, which had been held for a long time, turned white in an instant, and finally a flash of light flashed.

Morgan watched from the sidelines and couldn't help but sigh: "Teeth flashed, this has only been seen in cartoons." ”

Hermione didn't hear Morgan's complaints, she jumped excitedly, "We made it, this is real magic." ”

Morgan waited for Hermione to finish getting excited, and then said, "Let's do this to sell, what do you think?" ”

When Hermione heard this, she thought about it seriously, this thing was not necessary, so she shook her head decisively: "Don't." ”

"I'll produce the materials, and after I'm done, I'll divide you into three?"

"No, let's work on the next one, and I'll see what else can be done."

"Hermione, listen to me, we also cost money for the materials we do experiments, so we need to make this money, and don't you feel that we are not fully using this recipe? In fact, we can think in several other directions, such as whether this is harmful to the teeth, and for example, is there anything else that can be whitened besides the teeth?

So we need more experiments. ”

Morgan was there to persuade Hermione, Hermione was actually slowly tempted, she knew that she wanted to buy books, it would cost money, she couldn't just let her father pay for it, she had to earn a little for herself.

"Okay, but we'll only make a little bit of money."

Hermione hesitated, but finally agreed, and recommended Morgan a suitable candidate, her father, dentist Granger.

The two of them picked up the finished product and went straight to where Hermione's father worked.

Soon there was a time when they arrived at the clinic, and Hermione's father was looking at other patients, so he didn't come out, and Hermione was waiting in his office.

When Mr. Granger came out of it, he was surprised to see his daughter, "Hermione, why are you here?" ”

"That's the kind of Dad, my friend and I made a potion that can whiten teeth, we experimented with it, and the effect is very good, I don't know if I can sell it here with you."

"This .........," Mr. Granger didn't say.

Morgan thought that maybe he wanted to know how effective the tooth whitening potion was, and happened to see a yellowed tooth mold next to him.

"Uncle Granger, can I show you how this mold works?" Morgan said inquiringly.

The mold had been used for many years, and Mr. Granger really wanted to change it: "Of course." ”

"Thank you, Uncle Granger."

With that, Morgan placed the mold on the table, then took a small drop of the potion from the potion and dripped it on it.

When the potion drained, the teeth changed from yellow to white, and the other teeth next to them changed dramatically.

Mr. Granger's eyes were full of wonder, he really didn't expect that two children could actually make potions, and it was very effective.

"This ......... Did you really do it? ”

"Of course, Uncle Granger, Hermione and I worked hard to find raw materials, and of course, Hermione helped a lot."

Hermione then said, "Dad, can Morgan put this for sale with you?" ”

Mr. Granger thought for a moment and said, "Of course, I'll try my best to sell your products to customers, and if you sell the first one and it works well, you can make a lot of it." ”

Morgan is also very happy, the cost of raw materials is not very high, and it can be produced in large quantities, and the most important thing is that he usually does not use so many potions, and the price is very negotiable.

Morgan thought about it for a moment.

"Uncle Granger, how much does your toothpaste sell here?"

"Probably...... Around £3. ”

Morgan thinks about whether he can make a lot of money, which is really a good way.

"Okay Uncle Granger, then we'll sell it for 3 pounds, you can sell it with toothpaste, this will work better in toothpaste, and then get the money, I'll figure out what to do with Hermione."

Granger smiled and touched Morgan's head, "Okay, kid, what's your name, I still don't know your name." ”

"Morgan, Morgan. Potts! ”

Mr. Granger watched someone walk in outside, and then said softly, "Someone has come in, children, you can go back first, and we'll talk about this later, okay?" ”

"Okay Dad, let's talk about it when we go back."

As soon as he finished speaking, a guest came in from outside, and his teeth seemed to be very painful, and Hermione and Morgan went out without disturbing him with his work.
