I want to do cryogenics for my science fair project, and I found this on the internet.

It is possible but if I where going to do it I would use gold fish. I have heard they come back easier. You would have to gradually freeze them and then let them thaw naturally. We did do this when I was in high school and it worked.

No animal can naturally survive low temperatures temperatures associated with freezing, with the possible exception of nemotodes (very tiny worms). Arctic fish can survive very low temperatures by having anti-freeze proteins, but in this case freezing is prevented. If the fish gets cold enough and actually freezes it will be killed. A minnow would not have these proteins, so it would not survive the experiment. You could demonstrate the fact that they die in a cooling experiment, but people may be unhappy with the idea that you are killing fish.

You can do this with goldfish by putting them in liquid Nitrogen or liquid Oxygen but you have to be quick and I would not suggest you to do to too many of them because afterwards, they slowly die of gangrene.

I don't think so.
