Standing on balloons!

Today the Year 3 and 4 science club had great fun exploring how many people could stand on a table that was sitting on balloons.

Our predictions were that only 1 or 2 people would be able to do it. Well, have a look!

We ended up with 11 children on the table before a balloon popped!

Then we thought about trying it with only a few balloons - one on each corner and one in the middle...

We made it to 11 people again!

We are wondering what happens if we have a bigger table and fewer balloons or more balloons. 

Why do you think the balloons didn't pop?
