What is the purpose if this very odd request? Tell us what problem you are trying to solve.
as i stated in the orignal post, im trying to wake up early to start going to the gym at 3, then to school at 6. my mother is a teacher at the school i go to, so i have to go with her. im a very deep sleeper, so regular alarms dont work. i usually wake up at exactly 5:11 AM EST.

We all move around while asleep. How would your setup know which part of the bed your head happens to be in, or which way it is facing, when the alarm goes off? Of course, you could always spray the whole bed area, but I doubt that's what you want or what your mother would approve of.
An alternative solution would be to use the alarm to trigger a klaxon, or car horn.

as i said, it would be going off at 3 AM. i also live in a residential neighborhood, so the car horn/klaxon is a no go. i was thinking of putting the contraption on the stairs of my bunk bed as i sleep on the bottom bunk. i have drawn a rough idea of it, but i dont know how to use the clocks electronics to power the motor with the gear.untitled (1).png

The power driving that beeper is very small. I have a similar digital clock and have been needing a louder signal., but the beep is a logic level signal with very little power. So a circuit that uses that beeper signal is required. Probably a CMOS gate circuitto get higher powered audio,

You are going to have to do some investigation and turn up a few things like (one idea) a microphone and some sort of squirting mechanism that can be mechanically activated. Between the microphone and the squirting mechanism you will need some electronics to turn the small signal from the microphone into a timed pulse to drive the squirting mechanism.

Can you read electronic schematics? Are you willing to find the electromechanical squirting mechanism and gather needed electronic components? This will probably take a couple of weeks to gather the parts and get working. How does that sound?

this good enough?
A: alarm goes off. B: instead of beeping, the clock sends a signal to a motor with a gear. C: the gear with a rubber band turns counter clockwise. E: rubber band pulls trigger of spray bottle.
