Q&A Why the water drop by a stick through bottle hole slow down? [closed]

Question I was wondering what force make drop slow down? Does every time a drop push toothpick back into bottle? And of course how to solve it. Struct This is a bottle be pierced by a wooden too...

Why the water drop by a stick through bottle hole slow down?

# Question
~~I'd wondering what force make drop slow down? Does every time a drop push toothpick back into bottle? And of course how to solve it.~~
# Struct
This is a bottle be pierced by a wooden toothpick, made for continually drop water onto plant. The toothpick not connect to bottle, so no pressure make them "rigid".
Water height doesn't matter as explain below. 69 wooden toothpicks result 7.4g.
![Measure that water is 14cm height, toothpick is 1.072g.](https://physics.codidact.com/uploads/cseopysibnc48v744doa3hqube86)
# Phenomenon
The water drop interval continually slow down, worth note that even add water into bottle(to increase fluid pressure) won't speed it up(OR speed up obviously, I didn't measure it).
To plot the measure(manually count, mistake count include) `drop`(counts) by `time`(10*milliseconds) in Octave:
```
drop = 1:1:100

Why the water drop by a stick through bottle hole slow down?

# Question

I'd wondering what force make drop slow down? Does every time a drop push toothpick back into bottle? And of course how to solve it.

# Struct 

This is a bottle be pierced by a wooden toothpick, made for continually drop water onto plant. The toothpick not connect to bottle, so no pressure make them "rigid".

Water height doesn't matter as explain below. 69 wooden toothpicks result 7.4g.
