Cool, different. Needs more experiments, but the idea is cool. I'll try to add some.
Enjoy it. I love science. This app really tickles my fancy. Not only can I participate in experiments, I am learning, and I can do some of these with my children. I am looking forward to adding my own experiment to the community. I did not give it five stars for it is a work in progress.
