This object is a piece of apparatus for investigating air pressure in different locations on a wing. It constitutes two main sections connected by a number of clear plastic tubes. The main section (25.1) consists of a clear acrylic stand that supports various parts of the the instrument. On one side there is a acrylic tube-shaped holder, now empty. Stretching towards it is an orange plastic tube.
This plastic tube is connected via a rubber tube to a set of eight graduated glass tubes fixed vertically and connected at the bottom by a horizontal plastic attachment. This is the object’s manometer.
Coming from the top of seven of the glass tubes is a plastic tube. These connect to metal attachments on a wing-shape model (25.2). The wing model is made of transparent red plastic and has seven small holes in it. Each hole corresponds to a tube attachment. The wing section is attached to a metal rod so it can be affixed to a stand.

Aerofoil or Wing Section Demonstration Model
Primary Materials: Plastic, Glass, Rubber, Metal
On the base of the wing-shape model, two embossed stickers are affixed: “ZOO . 220” and “RM 136”. Each of the vertical narrow glass tubes is graduated and marked with “DISPOSABLE”, “PYREX” and “TD 20°C”. Some other writing on these tubes is obscured by the stand and unreadable.
There are no markings on the wing section.
Stand: 31cm x 16cm x 34.5cm; Wing Section: 28cm x 9cm x 6cm
This is an apparatus designed to investigate variations in air pressure over the surface of a wing at seven points. The air pressure differences are visualized as changes in height of liquid within the seven attached manometer tubes.
Good. Some parts are missing. The plastic parts are in good condition and all eight glass rods are intact.

Date of Manufacture:
This object was likely made at U of T to mimick the similar instrument made by Philip Harris Ltd. It was collected from the zoology department and appears to have been used as part of a Zoology course numbered ZOO220.
