My Car Failed

Today was a very sad day! My car didn't move during my presentation. I think it only moved 10 cm?! I got a D, better than an R right?! :-) I think it didn't move much because it was nervous, from all those eyes staring at it so hard!!! I should've placed my science car on the ramp for my 2nd attempt but instead I chose to use my pulley on the flat surface which I already tried with my 1st attempt and it didn't work! I guess I was being too optimistic!!! On the bright side, I got some Coca Cola slushie after school with Subie at the convenience store! :-)
