Today we tried an experiment to test
how much force is needed to burst balloons.
We called it “Balloon Surfing”.
Our question was: How
many children can stand on a table that is balancing on balloons?
Here
are some of our predictions:
§ The
balloons will slip out from under the table
§ It
will hold 9 children, the balloons will then pop and the table will fall
§ The
balloons will get squashed, not burst
§ That children that are the same size will pop the balloons
§ The
smaller the children the more that will be able to balance on the balloons
For
our experiment, we placed 35 balloons under a table.
We needed to make
sure the balloons were only half blown up and that they were evenly placed
beneath the table.
We also needed to have this experiment on the carpet.
We had 4 helpers who initially balanced the table onto the balloons.
Very
slowly each child carefully climbed onto the table.
Were we super surprised!!! We actually managed to get 20 children on the table which was balanced by balloons. There were so many giggles and screams as
we kept adding another child! It was such great fun!
Here
is why the balloons didn’t burst: When the balloon flattens out enough,
the pressure of the air inside the balloon equals the pressure of the desk on
the balloon and the balloon can support the weight of the desk.
