today, Oct 24, I was planning to do a experiment sending a ball down a tube that will hit domino's and trigger a car going down a track. this will be hard to do for i need a ball small enough to fit down a tube that is small as a maker. At the end of the class i did not finish this and had to take it apart because we aren't aloud to use the science pieces as ours and not lit other people use is. I will have better luck at home and testing it at science class next week.
