Birthdays at Pacific Science Center

Celebrate Your Birthday with Science!

Every Saturday and Sunday, Pacific Science Center hosts a variety of science-themed parties for kids of all ages. The celebration includes your own private party room in our Seattle Rotary Discovery Labs, complete with festive decorations, cake and hands-on activities all coordinated to match your party theme. We provide everything so parents can relax and enjoy the party - leave the entertaining to us!

Pacific Science Center staff will dazzle your guests with a 40 min. Super Science Show and interactive activity, followed by a 20 min. liquid nitrogen ice cream demonstration that creates delicious ice cream right before your eyes! Then enjoy the second hour with your guests in the party room. When the festivities are over, everyone can enjoy the rest of the day exploring Pacific Science Center's exhibits.
