SPRK is created when:

  • BTRY is placed within 2 pixels of any conductor except INST, INWR, PTCT, or NTCT.
  • ELEC, non-brown BRAY, LIGH, or THDR hits a conductor.
  • PHOT hits a layer of PSCN with NSCN behind it.
  • PSNS, TSNS, DTEC, VSNS, LDTCor LSNS are activated
  • CLNE with ctype SPRK is next to a conductor
  • VIBR or BVBR has a life between 1 and 300
  • DLAY with a life of 0 is next to NSCN
  • PTNM is next to HYGN and OXYG


Creates a current of electricity and is used to turn powered materials on or off.

SPRK cannot be placed alone, you need to put it on a conductive material. SPRK can be blocked by INSL in most cases. As long as there is an INSL between the two conductors, it will not go through. Some special elements won't be activated through INSL either, although some will anyway (like PSTN). Some elements have special rules on which other conductors it can conduct to, see each element for help.


SPRK can travel through most conductors every 8 frames, with 4 frames of activity and then 4 frames of rest before a conductor will receive any more SPRK. SPRK travels twice as fast through GOLD, PTNM, or SLCN as it does through most other conductors and one quarter as fast in WATR. The travel time through INST is the same for any length.


SPRK produces heat when traveling through most conductors. TUNG produces the most heat this way, getting up to 3323.25°C. IRON, METL, and BMTL reach 390.68°C. Unless heated, BRMT will rise until just under 400°C before dropping to reach around 391°C. METL, BMTL, and BRMT will turn maroon when heated to these temperatures. MERC reaches 35.82°C, expanding if not contained. ETRD will hover between around 31-41°C unless it produces plasma. PSCN and NSCN jump from 25.20-48.27°C. INWR heats to exactly 22°C.

INST, RBDM, LRBD, WATR, PTNM, GOLD, TTAN, SLCN, and BREL do not heat up when conducting.

Some conductors will actually cool down when heated above a threshold and sparked. ETRD cools to its temperature range, INWR and WATR cool to 22°C, PTCT cools to around 21.6°C, and NTCT cools to around 21.6°C. TESC is strange in that it, in small amounts, it actually cools itself down to near absolute zero, but in large enough amounts can heat itself with LIGH to max temperature.


A must have for all electronics. Many different uses.
