ExxonMobil Second Thursday Free Family Night brings an evening of hands-on fun to Children's Museum Houston in Houston. Every second Thursday, the museum throws open its doors for an extra stretch of non-stop exploring with minds-on exhibits, mind-boggling experiments and bilingual story time. It's free and open to all ages, so the whole crew can get in on the action. Bring the kids, grab your favorite grown-up buddy and enjoy a fun, easy night out.
