I was reading this post on Dan Meyer's amazing blog a while ago and thought it was great.
Then a while later I saw these amazing light paintings from the exploratorium and had an idea!
By throwing my bicycle light and taking a long exposure photograph I was able to get this image of a beautiful parabola.
After importing it into geogebra and looking at the projectile motion wiki, I made this:
If I had marked distance it would have been interesting to try and find the velocity I threw it.
This was also inspired by Radiolabs parabolas video.
