When I was a kid, the idea honey kinda grossed me out.
I always thought of it as "bee spit".
I'm putting 15 milliliters of
organic, local honey in this test tube.
We're gonna seal it up with a silicone plug, cap it
and then heat it to the point the failure with a torch.
I started to film this several days ago but the
The sky was pretty overcast and the lighting was pretty bad.
so I this left the test tube sitting there
I just left the test tube sitting there.
The temperature of the test tube was only about 35 degrees Fahrenheit
(or a few degrees Celsius)
Despite the cold temperature, the test tube is made a Pyrex
and it's a pretty good quality I'm impressed with these things so far
and the he didn't crack it...
there was no thermal shock
the heat from the flames is hitting about an
inch above the bottom. It's not
directly on the bottom
I wanted to see what kind of effect that would have this time
Honey is made up a lot of complex
sugars. The sugars that it includes is fructose
glucose, maltose, sucrose
and it has a a percentage or water
usually around fifteen the 20 percent I believe
what's interesting about this is there's a
layer of strata. I believe
where the heat is the hottest, is about an inch above the bottom
The honey is actually caramelizing
the honey below isn't get as much heat so it's
an insulated from carmalizing
As we have seen in
other experiments.... when the substance turns black
watch out! That's usually a good indicator that it's ready to blow.
Also you'll notice that the bubbles are forming in there will suddenly
drop right before it blows
You'll notice that the flame was
also blown out. Let's watch it again
on another camera further away
Now watching it in real time
you with think the thing just exploded but that's not the case
The pressure got up so great that it pushed that
high temperature silicone plug up.
...and it pushed the cap off with it. We can see that a little better here. (1200 FPS)
and as that superheated
high-pressure caramelized honey went shooting out
it propelled the test tube down
like a rocket and it still had
honey in there flashing to steam
when it hit the top of the table and then
the impact made it explode. There was still pressure inside
just a big nasty sticky mess
really what happen here notta lotta
a vaporization there was a lot of brown
crud all over the place. My back drop everything anyway I hope you found this
interesting it was fun to make
thanks for watchin now this is a recap from the
Dawn dishwashing soap the cap was pushed off
the test tube slung around and there was still
lot a residual pressure inside when it shattered
on top-of-the-table anyway thanks again
so long!
