Footnote from intertext

Question

I want to be able to send footnotes from intertexts I use within align. Is there an easy way to accomplish this (say using a package)?

For example,

I am a little teapot
\begin{align}
this &=spout
\intertext{Here is my handle,\footnote{(one hand on hip)}}
&=stout
\end{align}
these footnotes get eaten up.

Answer 1

You can issue a \footnotemark inside \intertext and outside align environment place the \footnotetext to get the footnotes inside align.

\documentclass{article}
\usepackage{mathtools}
\begin{document}
\begin{align}
this &=spout\\
\intertext{Here is my handle\footnotemark,}
&=stout
\end{align}
\footnotetext{(one hand on hip)}
\end{document}
