    Haha, oops I knew there would be something that I would forget :p

    DOF Science - Question 1 Part A
    1.
    a) C =Q*V should be C=Q/V
    b) Measure of Capacitance
    c) Ewald Christian von Kliest and Pieter van Musschenbroek (Image 3)

    2.

    n. Someone who is against everybody (Antibody)
    o. Relatives expecting you to do things for them (Blood Pressure)

    If you got part of the word correct you scored 1 point.
    I also allowed these answers for 2 points:

    g. Tiny people (Microorganisms)
    o. Relatives expecting you to do things for them (Kinetochore)

    DOF Science - Question 8
    The most common look for Cara is:
    Green eyes
    Black hair

    Freckles


    And there you have it :)

    Edit: I only need one more winner from Fantastic Contraptions to send me their designs and the poll for the Honourable Mention will go ahead.
