How can i do this?
Question:we have a wooden raceway a that is sloped downwards. you put 4 cars in, lift up a gate, and they go down on a slope. this is about 5 feet long. but sometimes, it's hard to judge which car got down first. is there a way to make something to tell which car got down first. sort of cheap, like not 10 dollars. my friend always lies to win and i want to have proof and it would be cool
Answers:
hang a loose "paper door" over each lane and watch from above as cars go through
not 100%, but it is cheap
get a digital camera from one of your parents and take a photo finish. Then you can see and then delete. High tech and you already probable own one.
