4M Crystal Growing Science Experimental Kit - Easy DIY Stem Toys Lab Experiment Specimens, A Great Educational Gift for Kids & Teens, Boys & Girls

No tengo fotos pero funciona bien, si se generan los cristales. A mi sobrino le gusto mucho. Juguete además de entretenido, didáctico para inculcar interés científico en los niños

Very affordable, fun activity! The crystals started growing within hours. You definitely have to follow the directions and times to a T to make sure they grow correctly. Our pure white one, small one grew the best. I am tempted to buy another kit and figure out what exactly causes better crystal formations...is it the "coloring seeds" and their shape/size?...Some of the seeds are mere granules and others are bigger, similar to a tiny rock. Maybe just putting 1 larger "color seed" is better for the smaller container?...The varying sizes of the coloring seeds also make it a little difficult to accurately measure "one scoop"...but overall definitely a fun experiment and better than watching plants grow! lol...younger kids definitely need some help as well.

I genuinely enjoy this product—it’s practical, durable, and worth every penny.

Todo muy bien, espero que se formen adecuadamente los cristales. Quiero indicar algo para los futuros papas que compren esto, supervisión maxima si lo hacen con sus niños, y mas si son super curiosos, ansiosos e impacientes, el mio termino metiendo el dedo y hasta meterselo a la boca, todo bien, pero aun asi uno creyendo que los estamos vigilando y se puede llegar a fallar.

All good, no dislikes
