I’m always accidentally dropping tablets on the floor and watching them scoot away beyond reach (only later to attract the attention of passing pets or children).
Today’s invention is a pill shape consisting of back-to-back cones. When dropped, this will roll in a circular arc with limited radius and thus its final location will be predictable…making it safely retrievable without calling a plumber.
This would be no less easily swallowable than other geometries but it might also need a coating of gel (such as the cod liver oil pellets I take) in order to limit the roulette wheel bounce effect.
