Räkna åskan — hur långt bort är blixten?

Hur långt bort slår blixten ner? Räkna sekunderna mellan blixten och knallen: tre sekunder är ungefär en kilometer. Ljuset kommer direkt, men ljudet hinner bara 340 meter i sekunden — så väntan ÄR avståndet. Här mäter du ett åskväder själv, blixt för blixt, medan det går rakt över dig och vidare.
