POP GOES THE BIG LITTLE WATER BALLOON
With the helping hands of four-year-old Ella Babcock, Susan Hammond of the Big Little Science Centre on the North Shore demonstrates what happens when a water-filled balloon in a pressurized container is suddenly released. A little work with a towel soon had the test bench ready for the next demonstration during the weekend show at the Holt Street centre. The Big Little Science Centre is the perfect antidote to the winter blahs, with fascinating demonstrations every Saturday. For all the information, go online to biglittlesciencecentre.org.
