A free, family-friendly science fair hits Leeward Community College's campus this Saturday, and it's good news for anyone looking for cheap weekend fun with the kids.

• The 36th annual Discovery Fair runs Saturday from 9am to 2pm, completely free with free parking.
• Over 30 hands-on activities are planned, including chemistry demos, bubble geometry, arts and crafts, and games for all ages.
• One featured experiment uses a special salt that releases oxygen when heated, causing gummy bears to smoke and burn in a safety-shielded tube.
• No tickets are required; families can walk in, grab a map, and visit any station in any order.

Outlook: Organizers expect another well-attended turnout as the event continues its decades-long run of making science fun for kids.
