they serve cold food with dry ice in a cup in the middle of the dish in restaurants right? My sister started adding more water and some melted ice-cream and bubbles started to form! And after every bubble popped, the gas would shoot out at different directions...!
@Spaghetteyes It is water vapor from the air (or if in a beaker like this water from the water int eh beaker frozen around it).
Having said that, if you don't know I would strongly advise against consuming it, especially if it was in a science classroom which could have all sorts of contamination.
@obillyify It can be handled safely in small quantities or for short periods of time. After that it isn't too exciting, a cold burn which can lead to frostbite.
@BionicleFreek99 Dry ice doesn't melt, it sublimes which means it goes straight from solid to gas. The rate of sublimation in the water is usually faster because water coming so close to its surface causes it to warm up all over versus limited contact with gases in the air.
Pieces this small will not go all night and there is a problem with putting dry ice in water- eventually the dry ice cools the water around it enough to form water ice around it which actually slows the rate of sublimation.
its the transformation of solid into gas because the dry ice molecules are moving slower as it touches the water the energy from the water creates energy in the dry ice which causes a chemical change. we learned about that today
Wow man cool, Ive been through Russia before, I live over in Erie, Pa. I also have been doing some research on dry ice myself the past week, and I am pretty much sure I know how to build a homemade smoke machine. I have built the actual machine, I just cant seem to find a place to buy the dry ice. Would you know where I could find some? Also, I was wondering which would cause more of a smoke effect, big chunks or tiny pieces? I would think tiny pieces because it has more surface area, right?
Due to liability issues I cannot tell you where to get dry ice, but a simple internet search would probably turn up suppliers and other venues.
And yes, tiny pieces=large surface area= more fog. The only issue with this is that the fog is slow to be generated without the addition of water, but tiny picese will freeze water around themselves and become encapsulated which can cause them to stop giving off fog temporarily until the gas pressure can crack the ice.
That makes sense considering the temperature of the dry ice itself is colder (or has more lack of heat)than the frozen state of Water. However what if there was more water than Dry Ice? I think I know where we are going with this but I want to be sure?
When there is more water than dry ice, i've found the freezing issue to be a bigger problem because it is easier for th gas to get trapped and encapsulated in the water ice.
Ok Thanks! I JUST ordered dry ice last week. I should be getting it an day now I'll be sure to test it out. Thanks for your help, I appreciate it. I'm going to test it out and post it when I get the chance.
how is dry ice formed?

@receivejesusnow Usually from the release of high pressure CO2. I don't make mine I purchase it or have it donated from a local yogurt making plant.

@receivejesusnow I've never heard of that being done, but it sounds like you are describing dry ice.

Whats the water thats made when the dry ice evaporates???? bc i drank some with my friend at school one time...

@mrericsully Yeah because it tasted like tonic water when we consumed it.

TAKE OFF THE GLOVES AND TOUCH THE ICE AND LETS SEE WAT HAPPENS

will the dry ice melt in the water or will it go all night?

at around 2:30 i love how he just flicks the piece of dry ice and it keeps going
