Trying to fill a JD bottle for a lamp in a biker bar.?

Broken chain Master link- old Harley riders will recognize them. If you can stop at a glass maker for technique- can remove the bottom and insert various bits and pieces like burned valves that won't go through neck. glue bottom back on and have lamp base just cover seam. The drill to remove involves careful glass cutter scraping a deep line and a alcohol soaked string set on fire in the groove, then a side tap that makes a clean break on the heated area- works 3/4th the time. the time when it shatters? just need to empty another bottle of Black Jack, preferably down your throat. wait until next day to retry.

spark plugs aren't a bad idea... do you think they'll fit though? the mouth of the bottle is 1" in diameter so it can't be bigger than that. I don't think the light bulbs will work but maybe spark plugs. chain links and all that mixed in would be good. The only thing is those aren't specific to bikes. Anything a bike has that a car doesn't?
