Experiment
Place
(not push) the marble on the top of the guttering to roll towards the
blocks. Count
how many move or fall down. Build
the bricks again in a different way (another bond) in the same spot and
try again. Find the strongest way to build the bricks.
The strengths of different types of bonds (patterns of building the
bricks) can be tested as shown below:
You need some rectangular blocks, a length of guttering propped up at one end, and a big marble.
Build the blocks in a regular pattern a short distance away from the guttering.
