bNosy video 12 - balla lyftande ballonger

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
