We made our Beauty & the Beast rose dome much the way Mr. Lowell did - big glass dome (boy was THAT hard to find), rose petals attached to little self-stick magnets to hold them on and monofilament fishline running down through a gold plant stand and below through the platform.  We also cemented a vase to the plant stand to hold the rose, and had two roses to drop petals - one with three droppers and the final one with one.  The glass dome actually looks exactly like the one in the Disney movie, right down to the molded glass knob on top.
