Faltan más experimentos en español, sería recomendable un librete de conceptos básicos y sugerencias para experimentar.

The optics are a little toyish, the mirrors just painted plastic, and still this gets five stars. The little laser line array thing is super cool.I'll probably demo some basics for my niece and nephew, but I'm keeping the lasers for myself 🤣

This is a super educational optics toy, and comes with a decent variety of positive and negative lenses and a mirror tool to illustrate key concepts about reflection, refraction, and focus. You can even demonstrate total internal reflection with the prism, if you aim it just right. It doesn't have a right angle prism, which would have really made this set complete.It comes with decent enough instructions and explanations, but it doesn’t come with batteries (you need 2 AAA). Note that you can adjust the lasers to be perfectly parallel with a small screwdriver, if needed, and you can turn each laser on or off individually. These are a lot of fun to teach with, and really help illustrate ray tracing concepts well.The box has a pattern and scale on it that you can supposedly use. But my box was kind of beat up, and I thought it was easier to just demonstrate on a plain paper. The power level of the lasers is not noted, so I would be careful and treat it as a class III laser, and exercise appropriate safety practices, and teach your kids appropriate safety practices. I’m guessing it’s probably class II, but you just never know, and it’s not labeled. I am going to subtract one star for the lack of any laser label, or safety warning, because this really is important. It has a "small parts choking hazard" and "don't mix old and new batteries" warning, but nothing abouty laser safety.Final Rating: 4 stars! Lost a star for not having laser safety warning -- otherwise an excellent educational toy. It should probably also come with a right angle prism to better illustrate TIR.
