WOW what a great idea and a wonderful presentation. I have done some math and i came to the conclusion that you need 1.956.000 segments to reach the 100 kilometer boundary of space.
18 segments : 92 CM total hight = 5,11
100 CM : 5,11 = 19,57 (19,5694716)
100 KM = 100.000 M
19,57 X 100.000 = 1.956.000 segments to reach the 100 KM boundary of space.
If there are some people ho are getting to a different number, please correct my hahaha
