why do soaking chickpeas click?
when soaking dried chickpeas, about 6 hours into soaking them in water they start to 'click'. every few minutes there's this click. anyone that soaks dried chickpeas must have noticed this, but why, what causes the sound?
i thought air was escaping from a chickpea but there are no air bubbles, no disturbances of the water at all!
is it just expansion?
