Algodoo

(I just had to write it all again just because my internet ran out of battery when I clicked 'upload file', oh god....)
Inspired by https://www.youtube.com/watch?v=kYmUJVE6Vo0, I decided to create my own set.
(Here supposed to be my explanation of my approach to calculate the whole gear ratio, but I don't want to write it all over again.... Please tell me your correct calculation of the gearbox ratio)
Each gearbox has a ratio of 640:1.
This scene has 2 gearboxes.
That means the ratio of 2 gearboxes is 409600:1!!
Please rate, comment, and subscribe. (If you need help in rating, ask me)
EDIT: 640:1 or 1:640?
