what the thing we can mix it with water to make fire?!!?

Answer 1

Fr element 87, alkali metal, very explosive on contract with water, and produces hdyrogen gas that is flamable. Once saw a video of 1 gram of the stuff dropped into a 10 litre beaker, simply just blew it to pieces.

Answer 2

Look up how to make silane using magnesium silicide, Mg2Si. That catches fire when added to water!

GERVALDF suggested you some SILICON COMPOUDs, e.g. Magnesium Silane.
Well, in effects chemists know several CHEMICAL STUFFs able to react against water to form explosives or flammable gas.
As Silicon does, other chemical elements belonging to the
"p BLOCK" in the Periodic Table may do it. See the following ones :
-) PHOSPHORUS may form Alkaline Metal's PHOSPHIDES, able to release PHOSPHINE ;
-) ARSENIC may form Alkaline Metal's ARSENIDES, able to release ARSINE ;
-) ANTIMONY may form Alkaline Metal's ANTIMONIDES, able to release STYBINE ;
-) BISMUTH may form Alkaline Metal's BISMUTIDES, able to release HYDROGEN ;
-) SULPHUR may form Alkaline Metal's SULPHIDES, able to release HYDROGEN SULPHIDE ;
-) SELENIUM may form Alkaline Metal's SELENIDES, able to release HYDROGEN SELENIDE.
About NITROGEN, I remark it may form Alkaline Metal's NITRIDES but water dissolve ammonia instead release it.

On the other hand, the "s BLOCK" relate the MOST FAMOUS METALs able to do it. See the following ones :
SODIUM, MAGNESIUM, POTASSIUM, CALCIUM, RUBIDIUM, STRONTIUM, CESIUM, BARIUM, FRANCIUM and RADIUM.

Finally, about CARBON, I remark F. WOHLER prepared Calcium Carbide able to release ACETYLENE, a very flammable gas.

I hope this helps you.
