With Halloween just around the corner, it's time to get out your decorations and get ready for trick-or-treaters! Build spooky ghosts and other moving decorations, learning about gear drives and other engineering concepts along the way. With tens of thousands of LEGO® bricks, we know your Halloween display will be simply "gourd-geous"!

Power up your engineering skills with Play-Well TEKnologies and tens of thousands of LEGO parts! Apply realworld concepts in physics, engineering, and architecture through engineer-designed projects with a video game theme.

For ages 6-11, registration required for children attendees only. The programs are designed to match the critical thinking skills of those who are 6 to 11 years old.

For children under 6 years of age we always offer LEGOs to play with in-house. Ask for them at the Children's desk.
