Need some help with my KELVIN'S THUNDERSTORM! what a name.. Answered
having some problem with kelvins thunderstorm.
i've set up 2 plastic cups on a wooden block
.the water drips from 2 tiny holes with wire to make it drop straigt down.
it falls through two copper wire rings (not perfectly round) with a diameter of 3 or 4 CM
then it falls in the same kind of cup but rapped in alluminium foil (outside and inside)
the copper rings are connected with the cups in alluminium foil (crossed)and finaly 2 little wires on each cup on the bottom have a little gap in between so i can see the spark.
but notthing happens...
what did i do wrong ?
