Question: does anyone know any ice cream recipes for a science experiment?

i have to make a science experiment for a high school science fair (agh totally lame). i was thinking about doing that icecream thing were you make ice cream. does anyone know a recipe that actually taste good?? thanks for your hepl if you do!!

Answer: 1/2 cup milk
1/2 teaspoon vanilla
1 tablespoon sugar
4 cups crushed ice
4 tablespoons salt
2 quart size Zip-loc bags
1 gallon size Zip-loc freezer bag
a hand towel or gloves to keep fingers from freezing as well!

Mix the milk, vanilla and sugar together in one of the quart size bags. Seal tightly, allowing as little air to remain in the bag as possible. Too much air left inside may force the bag open during shaking. Place this bag inside the other quart size bag, again leaving as little air inside as possible and sealing well. By double-bagging, the risk of salt and ice leaking into the ice cream is minimized. Put the two bags inside the gallon size bag and fill the bag with ice, then sprinkle salt on top. Again let all the air escape and seal the bag. Wrap the bag in the towel or put your gloves on, and shake and massage the bag, making sure the ice surrounds the cream mixture. Five to eight minutes is adequate time for the mixture to freeze into ice cream.

Tips
Freezer bags work best because they are thicker and less likely to develop small holes, allowing the bags to leak. You can get away with using regular Zip-loc bags for the smaller quart sizes, because you are double-bagging. Especially if you plan to do this indoors, we strongly recommend using gallon size freezer bags.

Question: Chemistry Home Experiment Help Pleeeeaaaase!!!?

I had to do an at home chemistry experiment for school (ilc). I had to put a galvanised nail, a steel nail, a penny, and a nickle in viniger and record the results in an hour, 3 hours, 24 hours, and three days. I didn’t see any results untill 24 hours at which point the steel nail was most corroded, than the galvanised nail. I didn’t see any results in the penny and nickle untill 3 days at which point the penny was more corroded and the nickle hardly at all. Also I don’t know what metel nickle would be considered in the metel activity series. I’m hoping someone else has done this experiment and wouldn’t mind sharing their results with me??????
I feel like since i am supposed to record after an hour and 3 hours that i should have seen some results by then.

Answer: You have great results.. What are you asking for?? Use the results and record it. Give your explanation.

A simple chemistry experiment

Question: Good science fair experiments? not tooooo complicated?

not very complicated yet cool and making u say WOAH! in specific i dont mean like a volcano, a robot or a can powered light bulb, etc. I mean something like experiments with chemistry and things like sodium, vinegar and plz dont suggest lame things

Answer: Lighting metals on fire. Like Magnesium burn with a certain color of flame. And I know Aluminum burn with a bright white flame. Do the research. It’s pretty cool or at least it was when I was 10 year old. And its very simple.
