pasta towers
GOAL—Build the most
efficient tower
5 cm x 5 cm block must fit
on top
Must fit over 10 cm x 10 cm
square opening
The bottom of this block
must be at least 30 cm
above the testing surface.
What is important in designing the structure?
Design (graph paper first)
Building process
Testing your structure
Analyzing –where did it break—why there?
Take pictures of towers
Use internet to search
Pasta towers or balsa towers
Look at the pictures of the towers
Write down what you noticed and
Towers are weighed before they are tested
Towers must support a loading block on top that holds a chain in the center.
This tower far exceeds the height requirement and well exceeds the minimum span
at the base. Rank is determined by the lightest tower
that holds the most weight, up to 15 kg.
This tower might have held the whole 15 kg, but it is definitely not the lightest.
Sand is loaded into a bucket hanging from the chain.
Some tournaments have a device that dispenses the sand
with the pull of a lever.
The entire outer cage structure on this tower is unnecessary.
The weight is held at the center, where the loading block is applied.
The extra pasta is simply adding more weight to the tower itself.
This tower is being protected in a cardboard box until
it is time for testing. This is very wise.
Joints are very hard to connect with pasta.
Note the excess glue strands that are adding (ever so slightly) additional weigh
to the tower. Hit them with a hairdryer to make them wisp away..
Joints need to be glued precisely.
Pieces need to be measured very
These joints have too much GLUE.
It adds too much weight to the tower.
Glue one side together. Packing tape was put down
first so hot glue would not stick to the table.
