Question: Mike and Sulley are able to activate the door when stuck at the kids camp by harnessing enough screams to activate it. If laughter is 10 times more powerful than screams, then why wouldn't child laughter (especially if there is a Birthday party, etc.) not activate doors from the "human world" allowing kids to go into the factory (monster world) all the time?
Answer: Well a door first needs to be activated from the monster side. See the doors of the human world lack the receiver for the energy they need to open the doorway between worlds (the red light on top). That's why in the monster world they hook a door up to a machine to activate it allowing the passage between worlds before any scream or laugh is made. It costs power to activate a door to allow a monster in. Boo was able to activate doors because she was in the monster world and her screams and laughs triggered the devices on top of the doors, activating them automatically. This was the first time ever a human entered the monster world.
Question: If Grug is so scared of things in the outside world and considers anything new to be dangerous, then why does he keep Guy with him instead of getting rid of him?
Question: Was P.L. Travers left-handed, as Emma Thompson portrays her when she is shown writing?
Chosen answer: It seems P. L. Travers was, in fact, right-handed. With just a bit of research, I found this YouTube video: http://www.youtube.com/watch?v=xeiEumLxTcM. At time reference 4:05, archive video shows Ms. Travers in her garden, holding a basket hooked on her left arm, and making clippings with a scissors in her right hand. Feeling convinced, I stopped, though I suspect further research (it's a six part biography) would yield other examples of P. L. Travers engaged in right-handed activities.
Only problem with the assumption that travers was right-handed because she trimmed plants with her right hand is that there were no (to my knowledge) scissors for lefties. I was born in 1955 and I am a lefty who cuts right-handed, wear my watch on my left wrist, and made other adaptations due to the fact that left-handers were ignored, and travers was born over 50 years earlier.
Answer: I do not know the actual answer to your question. However, I would like to point out as a lefty myself that we often have to use our right hand for certain activities just due to the fact that left handed options are not readily available. Scissors and shears are a great example of this. Very often you cannot just switch them to your left hand and have them work. They actually have to be put together to be left handed to work properly. Also, many left handed writers are also ambidextrous. For example I golf right handed but bat left handed so the two swings don't negatively affect each other.
Question: What I don't get is that if Thalia's tree had the barrier active all along while Luke, Annabeth, and Grover were kids, in the first film, how was the minotaur able to approach close to the entrance of the camp without being prevented?
Answer: Because the barrier prevents the monsters from entering the camp, not from getting close to it. It's the reason why after Percy used the fleece to strengthen the barrier, Luke and Kronos' army used the labyrinth to bypass it.
Chosen answer: The car is always shown in shots from the front so we can't see if the boot had a leak.

If the boot had a leak large enough to admit the starfish it would have filled with water and Gru would have drowned.
