ya man...that same tv show i was talking about earlier...they showed "powers of ten" using rings that were always 1 power of ten bigger than the last(i kno it dosent make sense, but click the link above and read the page). so it went: 1 power of ten, 2 powers of ten, 3 powers of ten, etc... all the way to 42 powers of ten. the they went smaller to -1 power of ten, -2 power of ten...etc. it was really cool! i loved it and im keeping this tape. i loved it so much, i almost cryed...*cough*
