how come if we pour a soda and put your finger in the fizz it goes down faster?
In: Chemistry
It also increases the surface area that the bubbles can pop against. This is why tilting the glass while you pour helps stop as many bubbles forming in the first place.
Touch a clean window and notice the imprint of your finger tip on the glass. That’s because your finger is covered in oil.
The soda fizz is made of lots of bubbles. Bubbles are tiny CO2 prisons. Oil on your finger breaks the bubbles freeing the CO2 prisoners. Without a prisoner the fizz collapses and goes away.
Oil on your fingers reduces the surface tension of the bubbles and then they pop. Kinda causes a chain reaction.
If you want to be even grosser wipe your finger on your nose first. Noses tend to be oily. Bubbles go pop faster.
On top of the other points that have been made, heat causes gasses to expand. Since your finger is warm it can cause the pressure inside the individual bubbles to increase from the gas molecules spreading further apart from each other. This along with increased surface area, and oils on your skin which reduce surface tension all contribute to a weaker, more poppable bubble.
wtf kind of question is this??? Get your finger out of your drink!!
I always thought it was germs popping the bubbles and not oil, this makes sense now that I’ve gotten over my germaphobia
Who puts their fingers in their soda?!
