Your are perfectly right. I wanted to suggest some way that might allow to
>see< through a clear glass cylinder (without noticing LEDs), enhancing the
illusion of extension. Frankly, to put my idea into work, you would have to
do quite a bit of experimenting. Fiddling with pressures, dyes, voltages.
Way too much work and expense for a party ;-)
Something that might actually work and look cool (though not at all like a
lightsabre) would be putting a chain of miniature plasma globe emitters into
a clear glass cylinder.

I mean: take a plasma globe, shrink it's diameter to 3 cm, take 50 emitters
and put them into a 1.5 m long glass cylinder. Fill it with Krypton, power
up and enjoy.
If you could get it to work, it would look very cool, I guess.
Still - way too much work and expense for a party ;-)
