If you switch a reasonable amount of your shopping there and get the "executive" membership, it will literally pay for itself. (Because it gives a few percent back, and that is enough to cover the membership fee)
I'll go one better.
A (non-spinning uncharged) black hole with diameter 1+5/8th inches (so it fits in the box) has a mass of about 2.3 earths.
(Near as I can tell QGP filling the whole box is around a ten billionth of that.)
Of course the box would Very quickly no longer be outside the black hole. QGP would also cause the box to no longer be a container in short order. To put it mildly.
A 1.44 "MB" floppy is 1440k, or about 1.406 real MB, and of that the space used by the FAT file system reduces it to around 1.38 free space.
For some reason I couldn't find the exact number and don't have any handy to check it myself.
I am pretty sure I know exactly what it sounds like. I had a talking alarm clock from the same era and everything that made sound electronically back then did so by using the same chips with the same samples as everything else. (Including pocket 'trick noise makers' and car alarms - those two categories even had some overlapping samples if I remember right)
It's made for him. It's his hole.
