Question 56
You are going to make a simple model of a metallic element and an alloy. You will need a selection of building bricks of the same size and a few building bricks of a different size.
Build a small tower using bricks of the same size. Your tower should be three or four bricks wide and about six bricks tall (Figure 7.28).
Now build a second tower of the same height, but use bricks of different sizes (Figure 7.29).
Gently push the bricks in the middle of your towers until the towers collapse.
Which tower was easier to push over?
