If you have young kids, youve probably grown accustomed to staying in on New Years and watching the Times Square ball drop before putting them to bed and passing out by 9:30. The sad part is, you probably dont mind. But your kids do, trust me. Coming to the rescue for kids in grades 2-8, the Pacific Science Center is hosting tonights New Years Eve Slumber Party. The first of its kind, the party will feature a fun night of science-related games and activities like hydrogen balloon explosions, rocket building, and liquid nitrogen ice cream demonstrations. Dont worry, its all safe and/or edible. The night will be capped by watching the Space Needle fireworks from PacScis ideal vantage point. No need to stay and chaperone: the event is fully staffed, your kids will be safe, and youll actually get to go out that night and do adult thingslike drinking while watching the ball drop and then passing out. Hmm. Suddenly your kids have better plans than you do, huh? 7 p.m. tonight to 9 a.m. Tues., Jan. 1.
