Yesterday, there was this relief teacher doing this super-cool experiment. I know it's hard to visualise but well, this is how it went...
He filled a plastic bowl with some water and sprinkled some pepper over it..
He applied some hydroxide stuff onto his finger and immersed it into the pepper solution, now the amazing thing happened: the pepper "repelled" and moved to the sides of the bowl almost immediately as his finger came into contact with the so-called solution! The speed was like 300000000000?!?
COOL!
