I confess I've no practical experience of this exhibit, but surely it must
be possible to make it work with an external fan, operating in clean air. If
the air then spins round inside a cylindrical display case, it would just be
a matter of designing a large-area, low-resistance, non-clogging filter to
allow air to escape from the top.
I wonder if this has been tried and found impractical? Or has everybody only
followed the original approach, as often happens with interactives?
Promoting public engagement with science
through a contagious delight in phenomena

Give people facts and you feed their minds for an hour.
Awaken curiosity and they feed their own minds for a lifetime.
