How my hydraulic model works

When you push the free plunger the hydraulic
system makes the second syringe move.

The syringe is joined to the cube which is
connected to a lever mechanism. The lever is the
mouth. The mouth is fixed to a strip of card
which is joined to the tail. So when the first
thing moves it makes the tail move.
