runaway shopping trolley is likely to crash into them.
Their other major vulnerability is to someone (often an oblivious young child) taking an item from the bottom level, thus causing the rest of the pyramid to collapse spectacularly.
Some supermarkets do have displays like this, but generally they consist of non-fragile items and are held up by cardboard support structures.
A common variant is to see someone just finish compiling the large stack only to have something bad happened to it. This tends to result in an "oh man" response from the stacker.
Commonly seen in a Grocery Store Episode.
- An advert for Marmite showing how much people hate the stuff has a trolley (cart) running into a display made out of Marmite jars. Which are made out of glass. And Marmite is sticky.

- One commercial for Wilkins Tea has Wilkins as a vendor at a supermarket next to a pyramid with Wilkins Tea on top and the other leading brand on the bottom. Wontkins pulls out a can of the other leading tea, and the pyramid collapses on top of him.
Wilkins: Another man who thinks for himself!
- The 1955 MAD feature on "Supermarkets" shows a malfunctioning shopping cart crashing into a pyramid of soup cans.
