  1. You could make one out of a safety pin, or even a paper clip. Then heat it over a fire till it glows red (loop only) and dip it into the water so you have a fleece inside the loop, not unlike that of a bubble blower.

    Step one, place the fleece onto the agar plate so you have a nice drop in the top right 1/3th of the plate, and strike it out all over that top 1/3th. Do NOT apply any pressure on the loop, or you will cut into the plate. Just let it rest on top and angle it towards the direction you are sliding.

     

    Step 2, sterilize the loop by holding it into a flame till red glowing, and let it cool.

     

    Step 3, Strike out 5 lines from the bottom half of the top 1/3th part towards the bottom left

     

    Step 4, sterilize the loop by holding it into a flame till red glowing, and let it cool.

     

    Step 5, Strike out 5 lines upwards to the left from the bottom half of the first 5 lines you made

     

    Step 6, sterilize the loop by holding it into a flame till red glowing, and let it cool.

     

    Step 7, Strike out 5 lines from the top half of the second 5 lines you made to the upper right, and wiggle the bottom line towards the center of the plate. Be careful NOT to touch the parts you already hit with the loop.

     

    Step 8, sterilize the loop by holding it into a flame till red glowing, and let it cool.

     

    And you are done. This ensures you will end up with free colonies instead of having a big blob on your plate.

  2. REPLY: I thought of you because I wanted to know if that molecular modeling kit you suggested I buy would in some way: as in I use it to make a model of any given molecule and could I or could I not, simply measure the different bond angles using a [ protractor ? ] I really do appreciate the advise you give me. ...Dr.Syntax

     

    Such a modelling kit has preformed holes, and does not account for polarity or atom size. In methane, all bond angles are 109,5°, in water of which the oxygen has the same orbital configuration as the carbon, the H-O-H angle is slightly less than 109,5° because the free electron pairs repulse eachother a bit.

  3. When im in public places such as the bus, school cafeteria or other places when your around many people i always look down.. reason : Its difficult for me to look in other peoples eyes. And always when i look at someones face when he/her is looking in another direction he/her instantly looks back right into my eyes like he/her knows that im looking at her.. i dont get it, can someone explain why it happens? Even if he/her is 10-15 meters away he/her instantly senses that im looking at him/her :S

     

    Strangely they feel the same way. If you look back again, you will notice that they are looking at someone else again. Makes fun games ;)
