For a Circus visit to be of lasting value you will have to consider carefully
how you follow it up. To help you, we are building up a resource
bank here on the site. There are:
virtual experiments complementing and extending the real ones,
information pages on the underlying mathematics,
suggestions to help your children build the apparatus for themselves.
