I had to make a video that had to do with kinetics for my class. Seriously, that was the only criteria. Click here to watch it!
I went for the good old neon food coloring to make it :) We tried using fluorescent polymers too but those were done in the dark with the exception of the UV lamp so it didn't come out as well. There's an introduction done by my research adviser, who happens to be British. It added some much needed humor :)
