Steve, we were just finishing up a project on how to design foolproof
products when your message came through. We concluded that there is no such
thing as a foolproof product, but we figured toy companies must be one
industry where someone actually takes the time to test totally inappropriate,
nonintuitive uses for their products, in order to get as close as they can
to foolproof, or at least reducing liability. We now see the kinds of
methods you employ. Thanks for the anecdote.
