Brilliant

So many tiny details make this set unique and brilliant. I choose to keep the Morse code and color spectrum displayed. I simply took the cover pieces off and added them to my Lego bucket. Love the flying bee, the DNA strand (spins), and carbon molecule (goes up & down), and all the other major symbols of science breakthroughs represented. symbols of science breakthroughs represented. Absolutely one of my favorite Lego sets.

Wonderful for STEM lovers!

This is my favourite set that I have built. I loved all the different details, I especially appreciated the hidden ones. The bee was a little fiddly and the app was more helpful to complete bee compared to the book. Once built, it is colourful and lovely to look at, as well as a great talking piece for visitors.

Love the nod to STEM

Absolutely love this build. Really enjoyed the Easter eggs, the Morse Code and Color chart. As a lefty, I didn't mind the DNA strand not going in the traditional direction. Appreciate the inclusivity, loved the George Washington Carver minifig.
