No science explained
While these "experiments" are fun to watch and feel, I felt the lack of scientific explanation really made these experiments fall flat. What is the point if you can not explain at least one scientific concept. I bought a bunch of these as gifts to give out for birthday parties we will go to over the course of a year. Every parent has said they wish they could explain why these plastics are growing and other plastics do not.
