In a few of the early levels of Particulars, there’s a pattern of having one or two more pairs of antiparticles available than you need to finish the level (for example, there are 3 particles and 3 antiparticles in a level where you have to cause 2 annihilations). This wasn’t the case for quite a while (because, quite simply, it’s more elegant to only have what you need in a level), until we realised just how infuriating and not fun it is to try and get a single down quark to annihilate a single anti-down quark.
Just how not fun? Pouring good beer down the drain not fun.
