Time for the next chapter! Again, I'd like to thank MarioDS01 for some of the ideas here! Not quite all of them, but there's a hint of an idea in there! Anyway, enjoy!

"Thanks for walking me back home, Arnold." Phoebe smiled towards the blonde haired boy as both of them were at the steps of Phoebe's place.

Arnold just gave a small smile as he said, "You're welcome, Phoebe. But you know I would do it for anyone, right?"

"Of course." Phoebe said as she opened the door. "You want to come in and we can get started?"

Arnold gave a nod. "Sounds like a plan."

With that, Arnold had followed Phoebe inside as Arnold smiled, "You know, I can't believe the day just flew by pretty fast."

"Ah, so you've breezed through that pop quiz, did you?" Phoebe smirked. "Just don't get too cocky. Remember, I'm the smart one."

Arnold sighed. "Phoebe, didn't we talk about this some time ago? You may be smart, and I won't deny that you're very smart, but there is such a thing as being too smart..."

"...for my own good, yes, I am quite aware of my flaw." Phoebe said as she sat down at the kitchen table, Arnold sitting alongside her. It wasn't until Phoebe noticed that Arnold's hand had briefly touched hers for a mere moment that she started blushing.

"No! Not again! Why am I blushing around him?" Phoebe thought in worry. In the corner of her eyes, she noticed Arnold was examining her face as she almost squeaked. "Oh no! He noticed!"

"Are you okay, Phoebe? Your face looks red." Arnold noted.

"Oh, I'm fine, really... you know, it's a little hot in here, I think I should open a window to get some cool air in." Phoebe started saying as she got up and started to walk off towards the kitchen.

Arnold could only raise an eyebrow, but gave a small smile towards her anyway. "She is pretty cute when she's all flustered..."

Arnold's eyes widened in shock as he turned away for a brief moment. "What am I doing? Why am I thinking Phoebe is cute? She just went through a break-up!"

As Arnold was shaking his head, Phoebe didn't notice as she started opening a window and sighing in relief. "Hope that bought some time... just repeat to yourself, Phoebe... Arnold is your friend... Arnold is your friend..."

Of course, as Phoebe turned around, she noticed Arnold, who was recovering from the head shaking, was staring at her intently.

"...Arnold has a very adorable fa- dang it!" Phoebe shut her eyes. "Um... so... what do you think we should do?"

"Hm?" Arnold looked at Phoebe in confusion.

"For our project. What should we do for our project?" Phoebe asked.

"Oh, right, of course, of course." Arnold said as Phoebe sat down. "Well... anybody can do a baking soda volcano, so that's out of the running."

"And yet, baking soda volcanoes ALWAYS gets the blue ribbons in science fairs... I mean, what IS up with that cliché, anyway?" Phoebe smiled.

"I know, right? I mean, come on, making fake lava and setting up a fake volcano, while cool, it's nothing new, yet judges treat it like it's a new thing? I don't think that's how that works!" Arnold frowned.

"What we need is a project that's new, something fabulous!" Phoebe smiled as another thought had creeped in her mind.

"Hmmm..." Arnold paused as he put a hand on his chin. "You know, I was thinking something along the lines of..."

"Lipstick?" Phoebe asked, her eyes rolled up.

"Lipstick?" Arnold raised an eyebrow.

Phoebe blinked a bit, before shaking her head. "Sorry, not lipstick. Sorry, my mind was on something else."

"Oh, OH!" Arnold said... then paused. "No, wait... maybe you're on to something with that..."

"Huh?" Phoebe asked.

"Well, I read it somewhere in a library book... some kid wanted to do human photosynthesis and experiment with turning himself into a plant. However, the teacher didn't really think it was a plausible project and assigned the kid a lipstick project." Arnold explained. "The kid went on with the human photosynthesis project anyway and it succeeded, but nobody believed the boy, at least until the President was involved. It was a... an interesting book."

"You want to do our science project on human photosynthesis?" Phoebe raised an eyebrow. "I don't think that's even plausible..."

"No, no, no, not that project. I was thinking we can do the lipstick project!" Arnold smiled.

"So... we make our own form of lipstick? I don't know, Arnold..." Phoebe started blushing again.

"It'll be brilliant! Yeah, it's no volcano, but a lipstick project can be an interesting group project!" Arnold said.

"But... uh, how will we know if any brand of lipstick we make will work? I mean, who do we test it on?" Phoebe asked, in concern.

Arnold stopped himself as he thought about it... then shrugged. "I'm sure we'll cross that bridge when we get there... anyway, would a lipstick project work?"

Phoebe just sat down and thought about it. She couldn't believe that one simple stray thought of her kissing Arnold and covering him with lipstick could just lead to her science project idea. Giving a small smile, she said, "All right... I suppose we can do a lipstick project. Guess we're doing a claim on that!"

Meanwhile, all the way out in Rhonda's mansion, Rhonda and Nadine were sitting together, trying to think up ideas for their science project when Rhonda stopped, cold.

"Are you okay, Rhonda?" Nadine asked.

"Nadine... I think I may have just had an idea... but it got claimed..." Rhonda said in a dark voice.

"Really?" Nadine said in surprise... then sighed, putting a hand on the rich girl's shoulder. "I hope it was a good idea... but how do you know it got claimed?"

"You're just going to have to take my word for it." Rhonda sighed.

And so, for about an hour and a half, Arnold and Phoebe started talking about the possibilities of lipstick and how to make something as complex as the object. Most of it was note taking, but the rest of it was just simple talk between the possibilities of lipstick. Of course, when Arnold looked at the clock, he yelped.

"Sorry, Phoebe, I hate to cut our session short, but I'm going to have to get going." Arnold said.

"I understand." Phoebe nodded. "Shall we pick up same time tomorrow?"

Arnold nodded. "Sure! Sounds good! See you tomorrow, Phoebe."

As Arnold took his backpack and started walking out the door, Phoebe gave a nod as she gave a warm smile. It felt nice, just working with someone who knew what he was doing with his mind... and is pretty cute as well...

Phoebe growled as she banged her head on the desk. "What is going on?"

With that, the fourth chapter is complete! How did you guys like it? By the way, that book Arnold was talking about is real. It's called "Top Secret" by John Reynolds Gardiner. It's a kid's book, but it's a pretty good read. If you see it in your local library, I suggest giving it a read. Anyway, read, review, criticize and suggest, folks!
