The Mayo Clinic recently Tweeted about an experiment that 8th graders in Rochester NY did to show how dangerous vaping was. The idea was they would compare developing zebrafish embryos developing in a solution of water and e-liquid, to those developing in just good normal fish water.
Obviously the e liquid fish died because… you know, generally anything other than normal good fish water is going to kill a fish. Especially a DEVELOPING EMBRYO. I think this experiment could have been done with coffee or dish soap and come to the same results, but don’t take my word for it.
