Review on 🌈 Magic Swirl Kaleidoscope for Creative Kids by Adam Quintana

My son is 4 years old and is really into 'science experiments' so we were so lucky to have all of this in one set to . We did an experiment with hard putty, which was cool, but then we tried making sparkling crystals and found that there were TWO packs of sodium tetraborate and ZERO packs of crystals in the box. We couldn't do a single experiment with the crystals and when we found the crystals were gone we couldn't return the box as we had done another experiment. The idea behind it is good. But I'm not happy that we didn't get all the content.
