Kites without a breeze

An original notice for an invented indoor exhibition.

The upstairs room will become a small exhibition of kites for one weekend. The exhibits will hang at different heights so visitors can see their shapes from below. None will be flown inside the building. Makers will be available to talk about the difference between a design that looks balanced and one that behaves well in moving air.

The exhibition opens at eleven on Saturday. Visitors who would prefer to look around before the talks begin can arrive during the first half-hour. Admission is free, and there is no need to reserve a place. Groups of more than eight should email beforehand, giving their arrival time and the number of people coming, so the room does not become crowded.

Write down the two details that a group of more than eight should include in its email.
