Dry ice is I believe carbon in solid form. At room temperature it immediately turns from solid to gas bypassing the liquid stage of matter. It is simply to warm for it to keep its solid form at room temperature. Its solid temperature is close to -200 degrees fahrenheit.
The dry ice is undergoing the process of sublimation, wherein a solid changes directly into a gas, skipping the fluid state, because the temperature of the water is significantly higher than the temperature in which CO2 can exist as a liquid in atmospheric pressure.
Dry ice is frozen carbon dioxide which is clear just like air. The "smoke" is water. The cold temperatures cause water in the gas phase (which is invisible) to condense into tiny water droplets which are visible because they refract light. In air you get very little "smoke" but it is visible. If you drop some dry ice in water you get much more of this smoke. The dry ice melts and boils directly from solid to gas and this gas motion helps push the water droplets upward.
you can actually spray or pour water on it
It's not "smoke", it's fog. Just like regular fog, it's tiny droplets of water suspended in the air.
Lol, been long time since I heard of dry ice me and my dad used to put some in a bottle mixed with other stuff and it would blow up lol... anyway: last time I saw I think it did yes :).
dry ice changing into smoke
Because of carbon dioxide
The idea is simple - drop a chunk of dry ice in some water; it will bubble and smoke. In practice, this is a little more difficult, because the dry ice will cool down the surrounding water and start to form a shell around itself of water-ice. Eventually the smoking and bubbling stops. The only way to keep this from happening is to keep the water hot, which increases the rate at which the dry ice is consumed. That's why dry ice isn't really used as often as people think it is.
"sublimation"
Sublimation can be seen when dry ice, or solid carbon dioxide, turns into smoke.
Dry ice, carbon dioxide, is more dense than air.
cold water makes dry ice closer to its freezing point. so hot water makes dry ice sublimate more
dry ice and water enjoy

When dry ice appears to give off smoke it is solid carbon dioxide subliming to vapor. The "smoke" is thus carbon dioxide gas. Dry ice is also often used in the theatre/television/movies etc. because it is cold enough to condense water vapour in the air to produce fog that may resemble smoke. Please see the link.
Dry ice doesn't "turn into smoke". Dry ice causes moisture in the air to condense, forming fog. This is a purely physical, not chemical, change.

Temperature causes changes in dry and water ice

dry ice is for mixing with water to make fog
The visible "smoke" is water vapor condensing from the surrounding air into tiny water droplets (basically, fog). Gaseous carbon dioxide is clear and colorless.
