i'd like to itemize a list of properties for my experiment protocol. What I want is:

there is some nice way to align itemized entrys in How to create columns within an itemize environment? and in columns/alignment with itemize but I can't get it properly done in the 2nd level itemize. Here is what I got at the moment
\documentclass{book}
\begin{document}
\begin{itemize}
\item Analysewaage
\begin{tabular}{p{0.4\textwidth}p{0.5\textwidth}}
\begin{itemize}
\item Topic Apple:
\item Topic Watermelon:
\end{itemize} &
\begin{itemize}
\item[] Something to say about it
\item[] Something to say about it
\end{itemize} \\
\end{tabular}
\end{itemize}
\end{document}
