Yup -- when I was a kid, many eons ago, there was a cheap toy or trick
called "Mexican handcuffs".  They were made of brightly colored woven
straw, usually in Mexico.  This was a small basketweave cylinder about
3-4 inches long.  You put a finger of each hand in the ends and couldn't
get free as the thing tightened as you tried to pull your fingers out.

Worked on the same principle as the wire mesh tube pullers that
originally came with the R-390, R-392, AN/GRR-5 R-174, and so on.  The
trick to release the tubes, or get free of the Mexican handcuffs is
basically the same -- you have to compress the mesh a bit.

Your "wire net" bulb extractor is probably also a basketweave "trap".  To
work without resorting to tape or rubber, the wire should be free of
oxide and not scrunched.  Some of these will work better if cleaned up
and pre-flexed a bit, then stretched out as much as possible to minimize
the original diameter.

Probably more than you wanted to know about bulb extractors, tube pullers
and Mexican handcuffs. ;-)
