The Milk Challange...

...was about building a bridge with a piece of paper strong enough to carry a milk carton.

This is how I made the first bridge.
I took a paper and folded the sides.
Then the bridge was finished.
But it did not work.
It was not strong enough.

Then I folded the paper into 7 triangles.
I did that because triangles and circles are the 2 strongest structures.
My teacher once told me that triangles and circles are the strongest.

Here comes the next try.
And this time it worked!

Once the raisins fell down, because I could not hold it still.
I used a box of raisins because we did not have any milk carton.
The box of raisins weighed 250g.
It is precisely the same as a quarter of milk.

Here I held the bridge downwards.
That made the raisins fall down.
And the bridge was destroyed.
