My school science fair is coming up in a couple weeks, and i need to get going on my project.

I think this is my question: How does the concentration of dyes affect their colorfastness?

but i need to know what to do... I think I'm going to dye a fabric with a natural dye (maybe blueberries or something?) and then let it set, wash it a few times, and see how it fades.

I'll do that with different amounts of dye each time, so i can test the concentration and how it affects the fading. but is there any special way that i can measure the degree of fading on the fabric? any other ideas? thanks, your help is much appriciated!

Right now it is 5 F outside, well below freezing. We have cases of pop out in the garage, that is not heated nor well insulated, but they seem to not explode. When I open a can, the pop is indeed slushy and begins to overflow, but they have yet to explode.

There have been a few times in my life that I recall a pop can exploding in the freezer. Why does it explode in the freezer but not in my garage? Also, is it "safe" to bring that pop inside now that it has been outside in this frigid weather for weeks?

I'm doing an assignment in science about theories that turned into facts as there was enough evidence to prove that it is true. You find a theory and research every aspect on it like; what was the theory, who was the person who theorized it, how was it proved etc. I'm looking for some really good theories that were proved, preferably a famous theory, so there would be more info on it, and it would be more easy to work with. Thanks in advance :D

They feel good and I first noticed it when in kindergarten my friend would play with my hair. I am wondering if there's a name for it and any other information about it. I know other people get them and they are not associated with fear or getting the willies.
