I was wondering if I could use a vaporizer to create a smoking effect without actually inhaling nicotine or other chemicals….just the pure water vapor. If this is possible, which vaporizers would be good for this?

I will be taking a UCLA course on multivariable calculus and I have only taught myself calculus. Are there any topics that I should focus on? I really need an A in the course, and I don't need people telling me that taking the course is a bad idea. I have consulted with my math teacher and other mathematicians, and this is what I am going to do.

Does acid affect cellular respiration? If it does, why? Also, does a higher pH mean more protons?

Hi, I have high blood pressure so I cannot ride any rides at Six Flags, but I am going for my end of year party. All my friends will be going, and my girlfriend is too.

I am getting one of the two boards and I am going to use it to get around town, but can ou do tricks with it? Most importantly, can you ride bowls with it? I was thinking of getting a board that could both get me around town and ride pools. It looks like a challenge due to the size but I think it is possible. Size 8 feet, 5'6" 130 lbs, 13 yrs. old if that helps. Thanks!

My parents are really mad after they caught me beating my meat. They lost trust in me after I denied it even when they saw. They won't let me got to sleepovers or stay home alone anymore. How should I deal with this?

Hi, I'm looking for a cruiser board thats light and small enough to carry around but also one that is able to ride bowls and do old school tricks.

I am thinking of trading these three game systems and 10+ games. I was just wondering how much it will come out to be.

I play the oboe in a band and symphony orchestra, and I was thinking about switching to the english horn or oboe d'amore. Some of the songs we play don't have english horn or oboe d'amore parts, so do I just play the regular oboe parts or even the bassoon parts? Should I just be transposing the notes, or what should I do? Also, are english horns and oboe d'amores really worth it?

I was just wondering if an Asian might have worn a tricorn in history, maybe through trade or immigration.

I really want a .22 rifle, specifically the ruger 10/22. My dad agrees to the gun, but my dad had cheated on my mom recently, so not much in my dad's word. I already have all the money and I know all the safety and everything about firearms. I have fired many guns including the barret .50 cal, but my mom does;t think I should get a .22. Do you guys have any suggestions in convincing my mom? BTW I am 13 years old.

I am an avid airsofter, and I would like to get into shooting real guns but there are some cons to it. I have some experience with real guns but I might want to purchase a gun. I only have enough money for one of the two choices, and they are a fully-customized IPSC Airsoft pistol, for training, and a .22 rifle, most likely the cz 452 scout. Both have their pros and cons but I would like to know if .22s are really worth it. The IPSC pistol is as real as it gets without the waiting period, and the sound, and the harmfulness. (it even has custom shell-ejecting features). Both are in the $200-$300 range, and they both have their pros and cons, but I would like to hear other opinions.

My dad always came home late, and he would always hide his cell-phone when he came home. One day he brought my mom some perfume and my mom was suspicious because this was a first. When my mom asked him to see his cellphone, he threw it on the ground and it is now destroyed. My dad has been trying to get my mom back, but my mom is adamant that he stay away. He just went to New York tonight for a business trip, but how do I get them to get back together and also prevent my dad from doing this again?

During the Qing Dynasty, King George III of England asked to open the ports of the then isolated China, and Emperor Qian-long refused. What were the relations between them? Did they hate each other or what?

I'm looking for a cruiser, longboard, or a skateboard for riding pools, and also getting around campus. Price doesn't matter, and I am pretty experienced with skateboarding, but I just want to know other people's opinions.

I really want a machete, but my mom won't let me get one. I won't kill anyone with it, and I'm actually gonna use it to help my dad clear the back yard of overgrown brush and trees. I was thinking of getting the smaller kukri knife, but is there a good argument that I could make to my mom to let me get one? I have enough money for it, and I am experienced with knives and swords. I have taken martial arts using swords for several years. I am 13 years old if that helps.
