Science Buddies: "Ask an Expert"

My name is Ladacious Mitchell I'm in the 10 grade and im taking chemistry. My question is which laundry detergent works the best between tide to go and gain. As a family I have been using gain I've always wanted to try tide to go but didnt until this project came up. Honestly i think gain stay focus on the smell than the power making clothes clean. but can tide to go work better without a smell. i think tide to go will work better because its on the go it can fit in my purse and even my pocket. i know the two of them have a lot in common but my question is which one works the best!

Comparing any competing products requires defining your test criterion. You could easily come up with two different test criterion and have the outcomes be opposite.

We have some info about designing survey-based projects here, if you want to investigate which one people prefer:

But you could also decide to test which one removes tomato juice better, for example, and then you'd want to think of all the variables to keep constant to insure a fair test. As Craig says, the answer completely depends on what kind of test you design. One might work better in hot water, one might be better at removing tomato juice but bad at removing grass stains, etc. More info in the project guide:

Greetings!

I am currently trying to do a bit of searching as to a simple home-made laundry detergent that would be compatible for greywater disposal on soil. Most of the recipes that I've found off the Internet etc involve various proportions of sodium carbonate & pure soap. However I've recently read in 'Create an Oasis with Greywater' that sodium compounds are nasty for the soil.

jennyj,
What question are you asking the experts here for help on? You should really start your own subject as your investigation on gray water friendly detergents isn't directly related to a laundry detergent brand comparison test.
