Floating Crayons

Another assignment about science. I would have written earlier about the floating crayons lab, but I had a hunch that it'd turn out like the last assignment...


 So. To business. This whole week back from winter break, we've been doing an experiment on the theme "Floating Crayons". We were allowed to pick any topic. And my groups picked changing the material.


See, we watched a show that had somebody making crayons float by putting salt in the water. Our group thought, well, what about sugar? Or baking soda? Or cayene pepper? Would you need more baking soda to make it float?


Well, we didn't bring enough cayene pepper. But here, I willl type up our results.


Salt needed: 2 TBS


Sugar needed: 4TBS


Baking soda needed: 4TBS


Isn't that weird? Now I am going to use some of my tenth grade math and figure out how often this would happen if they were all the same.
