Yes, because the freezer has to use more energy for the crushed ice.
No, in fact it will make it faster because Chocolate Syrup is think.
to make water freeze faster you put it some place that's colder.

Ice cream can be freeze dried. They sent this up in space with astronauts. You need to have or make a vacuum pump that turns the ice cream into a gas and dry it.

No, I am afraid not. To make ice cream you need to make an egg custard (milk + a little cream, egg yolks, sugar and vanilla). Then freeze that.

Salt because water especially hot water will make it freeze faster.
First you get an ice cream maker, then you freeze the bowl for the maker, then you mix the ingredients and then you put it in the maker, then you wait while it churns.
Why would you? I mean it's so disgusting! Only a weirdo would do that! It probably taste bitter and not so sweet. My advise DON'T DO IT!! :( A pinch of salt in anything sweet makes it taste better. You don't taste the salt. But in the case of ice cream, salt is sprinkled over the ice in an old fashion ice cream freezer to make the ice colder and make the ice cream freeze faster. I can't explain how salt makes the ice colder but it does.
