Hey! I am building props for a production of Beauty and the Beast, and have figured out the magical rose problem, using electromagnets, but am having trouble finding an economical method of building the large bell jar that it sits in. It needs to be plastic/acrylic since it's around 70 kids, and clear (obviously) with a diameter of around 10-12" and about 18" high. Any ideas? Possibly casting it from a mold, but have never done this, and not sure where to start.
