Pick the word, dial the collapse, build the card - then prove you can still find the original.
Pick one of the eight words for the blank, drag the absurd level slider from barely wrong to full collapse, and render the card. Then read mode: five cards, one is the original - point at it. No cat was harmed; the cat is a CSS drawing.
The frame "Scientists reveal the ___" is doing the talking; the word you drop in the slot is doing the breaking. Four absurd levels, from barely wrong at ten percent to full grammar collapse at the top. Render as many cards as you want, then take read mode: five headlines, only one of them is the original - the flat one-syllable word, the untouched frame. Point at it. The index card adds the renders, the peak level and the reading score into one number.
