Using Vacuum Gripper As Pressure Source

Has anyone attempted to use the VAC-KT Vacuum Gripper Kit as a low air pressure source? The video makes it appear to be a matter of simply starting the action 180 deg out of phase with the intended vacuum gripper function.

I don’t need much pressure, just enough to “pop” the eyes out a toy head that was built for this purpose. But I am concerned that the air might simply compress within the necessary length of tubing and not be able to move the eyes. Should the air not work, what if I filled it with water or some light, plastic friendly oil? The claimed vacuum hold time of 30 minutes indicates that it should not leak much.

Can anyone suggest a better mechanism (smaller, lighter, cheaper) for the job?

Thank you all.

The syringes should be able to provide a lot of pressure. No way for me to quantify it…

You can usually pick up a syringe for around a buck so it should be easy to test.
