Nikola Tesla's Cat: Mačak Sticker

3 Inch glow in the dark sticker

The inspiration behind Nikola Tesla's fascination with electricity was his black cat, Mačak. One evening, Tesla stroked Mačak's back and his hand produced a shower of sparks. This piqued Tesla's curiosity and he asked himself, "what is electricity?" Later in his life, he recounted the event in a letter: "In the dusk of the evening as I stroked Mačak's back, I saw a miracle which made me speechless with amazement. Mačak's back was a sheet of light, and my hand produced a shower of crackling sparks loud enough to be heard all over the house ... My mother seemed charmed — 'Stop playing with the cat,' she said. 'He might start a fire.' But I was thinking abstractly. Is Nature a gigantic cat? If so, who strokes its back?... I cannot exaggerate the effect of this marvelous night on my childish imagination. Day after day I have asked myself, what is electricity?"
