Yes.
Many (not all) relays have contacts that are normally open and another set of contacts that are normally closed. This way you have both options.
I used lawn watering valves.
 
Invert drive signal, depends on hi or lo side switch. But solenoids get hot unless rated 100%

In keeping with your method(s) for using parts borrowed from stuff around the house, how about a water valve from a clothes or dish washer? Mains voltage, of course.

Or a 12Vdc rig, like this: https://www.amazon.com/gp/product/B00MP5WY3Y/ref=olp_product_details?ie=UTF8&me=
Only USD$6.99

All can be kept powered (open) for any length of time, then power off to stop flow.

Is this what you mean?

BTW, like your video and the asides are funny.
