Choose a Party Theme
Astronomy

Design and build your own rocket, then you are cleared for takeoff. Launch your rocket into space and explore our solar system’s stars and constellations by creating your very own star map to take home. After that you will come back down to Earth to enjoy delicious ice cream made from some of the coldest stuff on the planet: liquid nitrogen! Finish your day at a Science On a Sphere show to see real time data sets of planet Earth and beyond.

Bugs & Butterflies

Become an entomologist and explore the world of butterflies and our other six-legged friends. Learn about the life cycle and bodies of insects, design your own butterfly to keep and touch a live Madagascar Hissing Cockroach. Afterwards we’ll make enough liquid nitrogen ice cream to feed a swarm! When your party is over, venture to the Tropical Butterfly House and see live butterflies flutter all around you.

Dinosaurs

Venture to prehistoric times and become a paleontologist as we uncover fossils from the past. Discover how fossils are made and how many different types there are. Go on your own fossil dig and assemble a dinosaur skeleton, then create a shark tooth necklace or dinosaur egg to take home. Lastly, dig into a bowl of liquid nitrogen ice cream! After your party, head into Building 1 to see the exhibit Dinosaurs: A Journey Through Time, where what you just learned comes to life.

Spa Lab

Discover how to make every day at home a spa experience with a birthday party in Pacific Science Center’s Spa Lab. Create your own bath fizz while investigating the chemical reactions that makes it fizz, froth and foam. Conduct an illuminating experiment with our glow germs that highlight the amazing powers of hand washing and soap. Complete your special day with cool and creamy liquid nitrogen ice cream and a trip to Professor Wellbody’s Academy of Health & Wellness to discover more healthy relaxation techniques.

Spy Academy

Investigate the undercover world of espionage when you receive a secret mission from Pacific Science Center Headquarters. Create an agent identity, assemble a message decoder and use your powers of deduction to decipher the code. Use spy techniques and tools including UV light and chemical reactions to reveal secret clues hidden in plain sight. Once you complete the mission, you will earn your badge in covert communications and celebrate with a scoop of liquid nitrogen ice cream!

Weird Science

Marvel as one of our expert science demonstrators gives you a private window into the world of physical science. Put your brain to the test with a plexer challenge, climb inside an electrostatic field with our Van de Graaf generator, and make your own “atomic” glow-in-the-dark gak to take home. Then experience the chilling effects of 320 degrees below zero liquid nitrogen as we make instant ice cream right before your eyes. Wrap up the day by discovering the many functions of the human body in the Body Works exhibit.
