Hello,
I saw the 'Fun with High Voltage' section, and thought it did indeed look like fun. However, I got some tin foil, and it wouldn't even stick to my screen. I tried another screen and it wouldn't work either (both computer monitors). Then I tried the TV, and it stuck great. Why's that?
Also, even on the TV, I wasn't able to get the slightest shock out of it. Should I leave it for a few minutes before touching it? I couldn't try that earlier because my Mum was watching something and told me to go away.
Thanks.

1. It only works on CRTs.
2. Some CRTs are coated with a transparent conductor to eliminate static
electricity. Those won't work.
3. The charge is built up only when the screen is turned on and off, so
you will have to turn it on or off (or on and off a few times) to get
a spark.

1. All the screens I tried were CRT's.
2. That's probably it. I can never 'feel' the static on the glass.
3. OK then, I'll try that now.

(Tried)
Still no shock

Is it possible that there could be a conducting layer and the aluminium foil still stick to it?

Try using old monitors, maybe the new ones are coated for protection... You could also try using a copper wire forming a zig-zag formation or spiral and taped on the screen of the tv..
