We receive many questions about the Laboratory’s official drop height. Here are the ones we find we can answer.
Why 72 centimetres?
The standard height was set in the Laboratory’s founding year by Professor Quill, who sat on a stool, extended one paw, and said “about there”. Gravel then measured the distance with a ruler and found it to be 72. Nothing about the figure is scientific. It is, however, consistent, which is more than we can say for the stool.
What happens at 73?
Nothing, according to the data. At 73 centimetres the object falls in exactly the same way, with the same sound. We maintain the standard because a standard is a thing that cannot be argued with, and arguing is the Laboratory’s second favourite activity.
Can we test other heights?
Yes, on request. Our Variable Height Programme offers heights from a low 20 centimetres up to a dizzying 140, which requires a ladder and a lot of paperwork. Please note that above 100 centimetres the cat must sign a waiver, which is a paw print on a napkin.
Does the object matter?
The object matters greatly. A pen falls with a clean little tick. A glass falls with a bright splash. A cushion falls with a sigh and is not covered by our standard. We therefore classify objects by mood.
Is it cruel to the objects?
The Laboratory takes the welfare of every object seriously. Objects are provided with a soft landing mat when requested, and are never subjected to more than three drops in a day. Objects who wish to lodge a complaint may do so by remaining on the floor.
Can I visit?
Public tours run on Wednesday mornings. Please do not bring unlabelled glassware. It will be tested.
Do you accept donations?
Why Not 70 Or 75?
Several colleagues have suggested rounder numbers. The Professor replied that a round number is the work of a lazy mind, and that 72 is a number with character. It is a dozen, times six. It is also, as Gravel points out, the exact height of the lab kettle, which makes it easy to remember and quick to boil.
How We Verify The Height
Each morning a technician lies on the bench and holds a ruler against the floor. A second technician lies on the floor and holds a ruler against the bench. The two rulers are compared and disagree by about four millimetres. This is recorded as measurement error and then, quietly, as a character flaw.
Does Height Affect The Cat?
A small number of cats become more serious at greater heights. At 72 centimetres a cat is relaxed. At 100 she becomes thoughtful. At 140 she goes very still and says nothing, which our team interprets as respect or as a plan.
Can I Choose My Own Height?
You may. The Laboratory will happily test your preferred height, though we charge a modest fee for the privilege and an additional fee for the ladder. We will not test heights measured in cats, since the cats object.
Where Can I Read More?
Our height standard is documented in the Laboratory Handbook, a leaflet of two pages, one of which is a drawing of a stool. A copy is available at reception, if the receptionist has not sat on it.
A Final Word
Please do not send us questions about height in imperial units. The Laboratory does not recognise inches, as no cat has ever been able to find one. Our measuring staff also object to the word foot, on the grounds that it is rude.
We do. Our most useful gifts are small ceramic items, cheap mugs, and any pen that has not been missed. Please wrap them carefully. Then please tell no one.
