pH indicating soap bubbles (Ben Krasnow - new channel name!)----make money online

I thought it would be cool to have a colored soap bubble that responded to changes in pH.  I concentrated some phenol red (pH indicator), and mixed it with commercial bubble solution.  Unfortunately, it was not dense enough to actually show its color. While investigating this, I noticed that normal soap bubbles lose their color as they become thinner

(due to evaporation) and eventually burst.  I tried to get footage of this color loss, but the bubble will not stay in the same place!  I started to develop a method to partially fill the bubble with helium to make it neutrally buoyant.

hey everyone I thought it would be

interesting to make soap bubbles that

contain a pH indicating dye the idea

being that the pH indicator starts off

one color and then as the bubble

interacts with the gases in the

environment it might change color so I

was imagining sort of filling a

container like this with co2 gas and

then if the bubble starts out really red

like this the indicator will change to

yellow when it acidifies and when you

when the bubble would sort of dip down

into the co2 it would acidify and change

color unfortunately this didn't work out

quite so well I started just by taking

some bubble solution here and adding

about a half bottle of this phenol red

this is a pool indicator pH indicator

for pool supplies and it wasn't nearly

concentrated enough so then I kicked it

up a notch I emptied out a few of these

into a beaker and boiled it down this is

dissolved in water and after you boiling

I had a fairly concentrated phenol red

and I even made this little form-fitting

container the idea was that I could use

the smallest amount of bubble solution

possible and it would still fit the

bubble wand in there so there do exist

commercial coloured bubble solutions I

didn't see any in the toy store near me

but I have seen it for sale online and

it looks like most of the reviews are

negative from angry parents who have now

stained clothing and stained houses and

stained driveways and such so apparently

we need a tremendous amount of colorant

to make the bubble actually not look

clear or not look colored because of its

thin film properties one of my ideas was

to have two gas jets next to each other

one blowing co2 and another blowing

ammonia and that way the pH of the

solution would change locally so you get

kind of a multicolored bubble anyway as

I was experimenting with all this I

noticed that plain old soap bubbles just

made with the the stock soap solution

would gradually lose their color as they

became thinner and thinner so if you

just blow a bubble and manage to make it

stay up in the

err I was using a co2 jet just this co2

tank and I would kind of follow the

bubble around with this to keep it up in

the air and after a minute or so the

bubble would become completely colorless

right before it would pop which was

really cool-looking so I was trying to

figure out a way I could get a bubble to

hang in one spot in space so that I

could film it so you guys could actually

see the colors fade away what I came up

with was the idea of adding a little bit

of helium to a bubble so I got this

other toy from the toy store it's

basically a big bubble hoop that you dip

down in bubble solution like this and

then it's got a fan with foam blades

that fills the bubble up so what I was

thinking would work pretty well is to

put a hose on my helium tank here and

just kind of hold the hose in the

vicinity of where this fan is drawing in

and then to get a neutrally buoyant

bubble we can start to blow this up and

then pop a little blow a little bit of

helium in there so it takes quite a bit

of practice but I eventually got almost

sort of the hang of it

so that bubble is a little bit heavier

than air there but it's pretty close

anyway so I'm going to continue trying

to figure out a system where I can get a

bubble to hang in air I know you can

support them on a tub of co2 but the

trouble with that is that it's kind of

sitting down in the tub and it's hard to

see the bubble itself it would be much

nicer if the bubble was just floating in

mid-air

so maybe adjusting helium a little bit

or using co2 Jets with feedback or

something like that but anyway I'll just

leave you with some footage of the

bubbles that I collected

you

see you next time byeTop Search Keyword : online earning, , make money online, earn money online, online earning, online earning sites, make money online free, online money income, earn money online free, money online, best way to earn money online, online income site, money earning websites, best online earning sites, easiest way to earn money online, earn money payment bkash, online money income site
