Celebrate your child’s special day in our party room with thirty minutes of exciting hands-on activities led by our enthusiastic birthday party coordinators, followed by cake and other goodies–a total of 1½ hours. Our coordinators will help you serve the food and clean up.

Before or after your party, you and your guests are free to play anywhere in our museum for as long as you like! (Note: The museum closes at 5 p.m.) Hands-on activities include:

Gak (Ages 4+)
Discover an amazing slime, and experiment as you try to decide if it’s a liquid or a solid!

Marbling (Ages 5+)
Use water-based coloring and shaving cream to make beautiful marbled art that you can take home!

Marshmallow Structures (Ages 7+)
See how stable a structure you can make using only toothpicks and marshmallows. Find out which shapes architects use to make buildings strong!

Shrink Art (Ages 7+)
Learn about scale and polymer chains as you make incredible shrinking plastic artwork to take home!

Flight (Ages 8+)
Learn how to make spinning helicopters, blimps, and paper airplanes, then see how your spinning creations react to one of our most famous exhibits!

Up to ten adults (including the birthday family) are welcome to join the party as chaperones. Additional guests cost $20 per adult and $15 per child. Maximum room occupancy is 35 people.

Activity Parties also include tablecloths, plates, forks, napkins, and cups in the two-color combination of your choice—plus an Exploratorium T-shirt for the birthday girl or boy.
