There is a rather good quiz question, ??What is the only foodstuff with a speed limit?? The answer, in case this picture doesn't give it away, is Heinz Tomato Ketchup or as us commoners are prone to say Red Sauce or Tommy Sauce.
The reason behind this is that Heinz are very proud of the consistency of their product. To test the quality of the sauce in the factory they pour some out and allow it to run down an incline. If it runs too fast, the batch is rejected.
The aim was to test Heinz's sauce against a cheaper competitor, ASDA's own brand. In the pictures the Heinz variety is at the back. The darker ASDA version is at the front. In the first, taken over 15 seconds on a shallow incline, both blobs have moved sufficiently to appear a little blurred but neither have really changed position.
In the second, again over 15 seconds, but on a steeper incline both have moved down the slope but it is difficult to say with any certainty whether one is quicker than the other. What can be said is that the Heinz one has held its shape better whilst the thinner looking ASDA one has spread out more.
Perhaps it's time for a new test: Blob of sauce on a flat surface how far does it spread out in a given time?
