First feed one pond. Then feed two at once. See what splitting your attention costs.
The point of this game: it's not about winning โ it's a little experiment on yourself.
Round 1 you tend one pond. Round 2 you tend two at the same time. At the end you compare. Most people
are slower and make more slips with two โ and that's the whole lesson: attention doesn't really split.
Round 1 of 2 โ one pond. Tap the matching colour-word as fast as is comfortable.
