But the three of us want to prank our friend and we need ideas. It can be anything complicated or even something as simple as THROWING A BUCKET OF COLD WATER.

  • Co-op at a Pharmacy?!?

    Being a graduate i've decided not to apply for university, so that I could come back and do a co-op at a pharmacy to gain experience. Being a pharmacist is my dream job, but now that i think about it, you need to go to at least college to fill the prescribed medication. Is the rest just a load of paperwork? Have I made a terrible mistake?

    Soooooo......... i really want to become a pharmacist but i've noticed that i'm slowing down with my homework. When i do chores, i tell myself that i have to do them eventually, so i might as well do it then and get it over with. I don't want to regret my lack of efforts in the future. Are there any motivational sentences that might help me with doing homework or planning ahead to study for a test etc etc.

    Thanks :)

    Based on two charts, one tells me that at an initial temperature of 24celcius, if you mix pieces of MgO with an HCl (at 1 mol/L) solution in a calorimeter NOT containing polystyrene or styrofoam, that the temperature will rise to 30celcius after 30 seconds, 35celcius after 1 minute and 39celcius after 1min30, WHEREAS the calorimeter WITHOUT the styrofoam and the same initial temperature shows temperatures going from 30celcius after 30 seconds, 32celcius after 1 minute and 35celcius after 1min30. MY QUESTION IS THE FOLLOWING: DO YOU THINK THAT THE STYROFOAM IN THE CALORIMETER INFLUENCED THE SLIGHTER DECREASE OF TEMPERATURE? Do you think that the temp. in the other one increased because of the metal inside?

    I'll make this explanation as short as possible. On tuesday im having a debate with 3 others (2 for and 2 against) on whether it is fair to be teaching religion in schools in general. I'm also supposed to incarnate a particular job where religion is involved. I'm supposed to be a priest (talking about the values in the bible and how they should be a part of a student's life), or a simple news reporter giving my opinions. I am FOR but I need some information..web site links, OR ANYTHING YOU GUYS CAN THINK OF, i'd really like to read what you guys have to say... THANKS :DDD
