Help!!! I need to figure out how a magic trick is done.It's were you pour liquid down a tube and it doubles

Question

There is a funnel connected to a box. Coming out of the box is a tube leading into a 1 liter beaker. When you pour 250 ml. of liquid in the funnel it fills up the whol liter beaker. How is this possible??? How is this done??? Please tell me how this is done A.S.A.P.

Answer 1

It's magic.

But you might think about how siphons work and what might be in the 'magic box' ☺

BTW. Going from 250 ml to 1 liter is called 'quadrupling', not doubling.
