This is the brainstorm set, with trees and tornado. The first brain-sprinkles are visible towards the rear.
The History of Brainstorming includes a real tornado. It is made of fiberfill mounted on a wire which runs up to a slider that can move left to right across the set. The sliding mechanism has a crank so the tornado can be spun. The bottom is stuck down with a magnet glued to the bottom of the tornado - the magnet sticks to a metal ruler beneath the bottom paper.
The next frame is coming together. Here, a new bumper is welded in place, the axle is positioned on a new axle plate. Replacement outriggers are are recycled from bits of the original trailer. This is done with an angle grinder.The rear frame members have large holes drilled through. A pvc pipe will fit here and run the length of the trailer. The pipe will be used to hold long poles for project screens.The new axle plate and axle secured.
