As Above So Below
I had an aluminum can of Coca-Cola explode in my car recently...It was a full unopened can that I accidently left in my car during my lunch at work...I came back out to my car 3 hours later on a break and found the can blown open with soda all over the interior of my car...I thought maybe the heat in the car caused this to occur but it also could be that they are also using less aluminum material to produce the cans...I keep seeing aluminium soft-drink cans at several local supermarkets that are burst open. Even in multi-can cardboard boxes, there are clearly ones that have been pierced and have spilt their contents everywhere. I remember reading over the pandemic that there was an aluminium shortage threatening the supply of such cans to the drink industry, so I am wondering if they have reduced the amount of material in each can as a cost-saving measure, thus making them more susceptible to being mishandled. Either that, or the amount of mishandling of them itself has seemingly increased recently.
The biggest issues I've had with sticky tape is with the masking tape and duct tape types...Most tapes aren't performing as expected and it seems that if I buy any other brand that is not affiliated with 3M products, then the tape doesn't not work well...3M brand does seem to hold up and perform well...sticky tapes.
I've noticed the flat spots occur because of the mechanical device used to retrieve the trolleys and run them en masse back to the grocer building...The operator starts and stops (mainly stops) the trolley retrieving device too quickly causing the trolley wheel tread to wear down quickly...Could be that the material used is now inferior and doesn't hold up well either...My local supermarket has trolleys where about 40% of them have a flat-spot on one of the front casters so they no longer roll properly. So the tyres of those casters are obviously not up to the job, as whenever one of the wheels gets jammed and cannot turn, a flat spot is immediately worn into the material. Sometimes these sorts of material failures are due to the fact that environmental legislation means that manufacturers can no longer use something that works, and have to choose instead from materials which do not work (think paper straws, although that has largely been a voluntary measure by the fast food industry).
