5 things you need to know this weekend
Set phasers to science because World Space Week begins
Grab your spacesuit as World Space Week begins its appreciation of skies, stars and planets Saturday. This year's theme, "Space: Guiding Your Way," focuses on satellite navigation. There will be documentary screenings, discussions with astronauts and even a Halloween-themed party in Tulsa. World Space Week began after a declaration from the United Nations in 1999 and has continued since.
Jews around the world observe Yom Kippur
Jews will fast throughout Saturday in observance of Yom Kippur, or the Day of Atonement. It's one of the highest holidays in the Jewish faith and serves as a time to forgive others and reflect on the changes of the past year. Fasting is an integral part of the holiday, which started at sundown Friday and will end at sundown Saturday.
I scream, you scream, we all scream for... video games?
Marin County Police officials are asking children throughout California to trade their violent toys and video games for something a little sweeter: a scoop or two of ice cream. Starting Oct. 4, families can go to locations on Saturdays throughout the month to trade their toy guns, video games and the like for Ben & Jerry's. Sounds like a pretty delicious trade.
