Bueno, what you want for 1 u not put batteries in series to 4 .. In more than 6 volts and 3V ur-led coup.
if u put 2 in parallel, then 2 more in parallel, the series-2-game would u UR 3 volts.
But each time, since the U-boat is filling up fast.
SO ... 4 take longer for the same juice.
No batteries applied to assembly in a waterproof container light .. Alka Seltzer then hand assembled in the vicinity of the opening of the PET bottles put any pressure on the development of the current for LEDs ..
Screws on the top of the PET bottle, but only 1 / 2 of severity, so that contacts seawater Seltzer.
