Yesterday we had the pleasure of showing our science experiment videos for school teachers at Skolforum in Stockholm. This week we want kids to bNosy about balloons! Why do some fall down to the ground and others float up in the air?
To carry out this experiment you need:
5 balloons filled with helium and attached with strings
about 15 small Lego figures
1 small plastic bag
