Iva had a great idea for my science assignment, unfortunately im now an Engineering student at uni, and that science assignment was due in year 10 four years ago......
But just for fun I might do it anyways.
Someone had the idea in my class to measure what brand of pen lasted the longest, but could work out how to calculate it, drawing lines and lines would be inefficient.
So they dropped the idea.
Here's what I am going to do (maby!)
- Weigh a full pen of each brand
- Draw a set distance of lines with each pen
- Weigh each pen
- Drain each pen of ink
- Weigh again
- W(full)-W(empty) = W(ink)
- W(full)-W(after lines) = Ink per lines
- ink per lines/distance = ink per distance
- W(ink) / ink per distance = distance of pen
