ID Code: N1-45
Purpose: Demonstrate a large angle rainbow.
Description: Light from a bright point source falls onto a spherical water flask. The flask acts as a raindrop, producing a nearly 360 degree rainbow. The rainbow is bright enough that it can be seen throughout the entire lecture hall.

Both the primary rainbow and the secondary rainbow, with colors reversed, can be seen. Slight adjustment of the flask on the sliding carriage may be necessary to maximize the brightness.
