Rusts metal. Turns plants (wood, vine, and seed) into powder.
Special properties

Seawater (also called salt water or saline water) is an artificial liquid element found in Powder Game. It can be made by adding salt to water.

Salt and water

Seawater rusts metal faster than water.


  • Seawater can't be frozen by ice or ice ball, unlike water.
  • For seawater and magma, two reactions are possible, which both happen if the player mixes a large amount of seawater and magma:
    1. The water in the seawater evaporates and leaves behind the salt and the magma is destroyed.
    2. The magma cools down and turns into stone. The seawater is unaffected for this reaction.
  • It turns metal and plants, which includes wood, vine, and seed, into powder.
    • This can be used to make "growing vines".
  • Seawater rusts metal at much higher speed than water.
  • Seawater is more resistant to magma than water.
  • Seawater turns ball into powder.
  • The player can make seawater text by either using the quick way or the hard way. The quick way is to make some steam text in stop mode, then cover it with glass. Press start, and the steam text will disappear. Then the player makes saltwater, and copy/paste it into the text holes in the glass. The hard way is to do the same exact thing, except use C-4 instead of glass. Then the player clears away the C-4 to make the text.
  • Seawater turns fuse into gunpowder.


  • Seawater is the fourth artificial element released in Powder Game.
  • It has the same color as Earth Editor salt water and was first implemented in Earth Editor.
  • In contrast to the implementation in Earth Editor, one cannot dissolve multiple dots of salt into one dot of water in Powder Game. Therefore, the seawater can not have different degrees of solution like in Earth Editor.
  • Players used to move faster in water than in seawater, but this glitch was fixed in version 6.2.
  • Seawater reacts with acid at a 1:4 ratio.
  • Seawater can be used as a quick timer with metal.
  • Seawater ball can easily glide on a smooth surface of metal, turning it into powder on the way.
