how fast do alka seltzer dissolve in different liquids. take like different liquids (water, sprite, vinegar, oj, and such) and time how long the alka seltzer dissolves in it. i did it couple years ago and got 1st
What I did was take 2 of the same pops and then cover one in red paper an one in blue paper. The theory was that more people would like 1 pop more because of the color. I proved this as more people liked red than blue. :D
Last year I did which bleach works best clorox brand, giant brand, and bloom brand. I cut up a white tee-shirt and washed the strips in the different brand. My teacher loved it, and everyone in the class said it was really good.
