Hi TwinkleToes
We bought all of them thinking we would get to them eventually, LOL!!!! We have completed Space and Germs and are on the Human Body right now. We did space and germs together because germs had experiments that took 7 days!!!! So I found that DS was good setting the long ones up provided you did one with immediate pay off. So we watched bread mold for a week but did red light in the closet, and painted a solar system. On amazon, people said the rainbow one was boring and other comments but no complaints so far, and DS loves the stuff, we got eye droppers, test tubes, etc. And he loved the MSB books so that set him up because it was presented the same way. So short version loved the first 3 and expect the next 4 will be cool just for the sheer act of doing it rather than the amazing science of it. He has read so much but this was hands on and that really appealed. Everytime we did it he would create his own experiment after, I have great video of yeast and water in the sink after watching yeast blow up a balloon!
