This evening we saw two consecutive TV adverts that left me virtually speechless. The first was an insurance advert that stated:
Most accidents happen on Fridays between 3pm and 6pm.
What is that even supposed to mean? Most accidents happen in a three hour period in each week?
The second, hot on its heels, stated that (presumably compared to the 'standard' product) their 'sensitive' product had a pH 10 times lower.
Now I can guess what this is supposed to mean, but let's suppose we take it at face value. If the standard product had the highest pH we can reasonably imagine 14 - extremely, corrosively alkaline, the same as caustic soda, 10 times less would be 1.4 - as acidic as gastric acid. If the standard product was 5.5 - the same as skin, the sensitive product must be like battery acid. I can only assume that this advert was not aimed at chemistry graduates.
Incidentally, I built the nearer tower with Exile #4 last week while Exile #3 was at school, when she returned she helped me build the 'copy' out of Lego - a very satisfactory if entirely pointless engineering project.
