Re: Crazy candle project

Hey you guys are awesome. This is for a magic trick as was spotted and
engineers are responsible for some of the greatest illusions ever
which is why I came here first. I am sorry about the multiple postings
(also on sci.electronics.basics) but I saw this group later and
thought it would be better here. So to clarify the trick , a cup
(4inches by 4 inches) made of copper is secretly loaded with a candle
and placed on a table and then revealed a few minutes later.

Mike posted a simple solution on the other group :
"Such complex and potentialy dangerous solutions to a simple problem.
Take a match and slice into the head with a sharp razor blade. Slip
a piece of fine wire into the slit and wrap it around the head.
Solder some larger gauge wires to the fine wires so the joint is
below the head. Secure the wires to the paper match stick with
masking tape.

The larger wires won't fuse when you apply a voltage, but the fine
wire will light the match. Fudge and practice until you can just
tilt the cup enough to let in light and get the flame near the wick
- if the whole contraption is inside the cup. You could hide it
behind the candle. Don't use a flammable cup. Placing the cup on the
table will extinguish the match, if it's in the cup. If you want
your audience to see that the cup is empty and there's nothing
behind the candle, make your own candle around everything - battery,
sensor, ignitor.

You should be able to set the match off with 1 or 2 batteries - like
the old 000 steel wool firestarter trick.

Followed up by :
How about use a lunar ignitor for a model rocket motor. It would only
need about 6V... maybe tie a CDS cell in there for the light sensor.

Ray"

I think Mike's idea would work pretty well and not get me killed. I'd
plan to encase the whole rig inside the wax. I dont know a lot about
light sensors (except that they exist). Whats a CDS cell that Ray
mentioned and where online can I buy one. Any better ideas?


Sincerely,

Andy
