Did you know that clowns used to "trademark" their clown face by painting it onto an egg which was then stored in a big vault? No-one was allowed to copy another clown's face - that would steal their spirit. And when that clown went to the "bigtop in the sky", the egg was crushed? Neither did I until I went to the exhibition!!! They had a table set up so kids could create their own clown face on a egg-shaped piece of paper using bits of scrap - they may not have any left after Billy was through though :)
When we got home we read a piece about clowns in other countries, and the next day did a clown craft - creating a clown from an empty toilet roll that I got from here - http://www.dltk-kids.com/crafts/circus/mtpclown.html.
