How to build a super column

What was today's experiment?

Today's Experiment was to build a super column and to do a sisomo (sight sound motion) on how to build it.

What is a super column?

Today I built three super columns and one of them was a flat sheet of paper the other one was circular and  the third was a triangle. I was trying to find out which of them had the most compressive strength.

  

Here are my videos on how to build a super column:

What happened when I tested my super columns power?

Well when I tested my two flat sheets of paper it collapsed without even holding it up for a second.

When I tested my two circular ones they held the rock for very short time and then collapsed, but it still worked better than the first sheets of paper.

Then I tested my triangular pillars they held up the rock for very long and still it didn't collapse.

Reflection of the activity. What did you enjoy/learn?

I learnt that triangular pillars were the strongest.
