how i made the ruler

i measured 1 cm lines i drew them with pencil then went over them with pen . i coloured every second part with permanent marker, i did this because  i have seen similar things in mythbusters where they use slow motion cameras to find the speed where as i will use just a normal digital camera

paper ruler

hello in this post i will talk about the paper ruler that i have now finished (see left) i hope this helps me measure how fast sphero is because it was a pain to make! I had to re-make it because the stripes were too wobbly :-(
