Open House

MagLab Open House Banner

MagLab Open House is a free, annual event for visitors of all ages! Each year on the last Saturday in February, we invite the public to explore the world's largest & highest-powered magnet lab, engage with nearly 100 hands-on demonstrations and meet our scientists and researchers. 

Thank you to the more than 8,500 visitors who joined us on Saturday, Feb 24th for MagLab Open House 2024! 

If you missed our 2024 Open House event, please check back later in the year to learn more about our next MagLab Open House in 2025 (on the last Saturday in February -- Feb 22, 2025). 

In 2024, we turned the lab into a Science ToyLand with special activities inspired by all of your toy box favorites- from classic building and spinning toys to iconic characters and modern favorites. People came and explored the science of toys and the creative fun that comes from play!

When: Open House 2024 has ended, but we will be back on the last Saturday in February 2025.

Where: National MagLab Headquarters Location - 1800 E. Paul Dirac Drive, Tallahassee, FL 32310 - View Google Map

Attack of the Acronyms

Acronyms (and their less cohesive cousin, initialisms) are one of scientists’ favorite communication tools. But their use — or overuse — can torpedo the chances of readers actually comprehending what is written.
