My memory may not be perfect, but with the bottle cutter, you were suppose to save the top (conical) part and glue it to the bottom (jelly-jar) part to form a “stunning wine goblet.” I guess they took liberties with the various definitions of stun.
I just remembered seeing soda pop bottles stretched into “beautiful” shapes. Seemed like they were everywhere for awhile, years ago. I never saw one made, but I think they were the results of another of Ron’s magic kits. Anyone else remember them? they were stretched and twisted and had obviously been heated.
Peace,
