Welcome to

A unique, indoor science center for kids of all ages.

Our NEW Kids-Only Evening Science Sessions allow you to Shop Peace!   

Feast your mind on this...

How does it work?

Important Notes about "dining in" at The Great STEMporium...

Ideal Ages: 5+
Important Note: There are choking hazards, and it's a very active environment (Read: can get loud/exciting) that requires your full attention to make sure the experience is safe and enjoyable for all the children you bring in. Sorry. Our menu doesn't have STEM projects for kids under 5.  We do have a basket of fidgets you can borrow ($6) for kids age 3 & 4 to keep them busy.

Adult to Child Minimum = 1 adult for every 3 children
Child to Adult Maximum = 3 adults for every 1 child
[These ratios are important for the enjoyment of all participants AND table space availability.]

You'll want to plan about 30 minutes to an hour for your visit.  Some families, who really really love science will end up staying 90 minutes or more!

Reservations strongly recommended for parties of 7+ 



Credit card payments only.  No cash.  We accept Visa, Mastercard, and American Express. 

Yep. There's plenty of parking in our shopping center.  There are 2 handicap spaces directly in front of the doors.  There is a ramp near the doors.  Our doorways, isleways, tables, and bathrooms are wheelchair accessible...even our big, special door that helps us keep all the magic inside!
