LEGO Periodic Tower of The Elements

A LEGO Periodic Tower of The Elements, a form of Schaltenbrand's 1920 Helical Periodic Table, by Enrique Barrajón, as shown on the LEGO Ideas website.

Enrique writes:

"The Periodic Tower of Elements is a complex LEGO project designed for students with some chemistry knowledge. It serves as an educational tool to help with learning basic chemistry and physics concepts. Building this model enhances skills such as patience, balance, attention to detail, and innovation—qualities essential for mastering abstract scientific ideas. Additionally, the model offers insights into architectural stability concepts like spiral staircases."
