What fun things to do for National day with kids in Singapore?

I LOVEEE to go for Picnics @ Marina Barrage! At the rooftop of the Marina Barrage there is a beautiful large grass area where you can view the Singapore Skyline, and be surrounded by other happy families and friends enjoying their national day celebration, creating an enthusiastic and happy vibe. I really enjoy it as the public is out as well and we can all get to know each other and enjoy each other's company !
