As the candles burn, the CO2 and H2O from the lower candle rise and displace the O2, extinguishing the flame of the taller candle.
However, when there were three candles, the two taller ones (even with different heights) extinguished at the same time.

Linguistic-
1- electrons build up on tip
2- electrons jump to ionized molecules in air, turning the flame blue
3- the 4 cm is too far to ring stand, but putting a conductor in the path (ions in the candle flame), then charge able to flow the 4 cm distance

We put the LEDs in parallel so there is enough voltage to keep them bright. The play-doh provides enough resistance so the LEDs do not burn out. The LEDs must be arranged to have proper bias ( current can only flow one way.

LEDs are directional (only work if current one way) and must be in parallel. Clay is higher R than play dough (so dimmer).
