the autotune one, like I said, because I
didn't have to help him. He just he was
working every it was happening. And I
don't know if you caught it. It was very
subtle. After I said, "That's evil."
Remember when I said that's evil?
Referring to a note goes in that's bad
and not comes out as good from a
microphone. And he said, "Well, that's
not evil. My wife puts on makeup, okay,
in the morning."
And then there's a pause
and then he leans over and says, "Is
that okay, honey, that I said that?"
He's co-owner of that business with his
wife. And his wife was just off camera
and was listening. So,
I don't know if there's hell to pay
later that night in that situation, but
it's subtle, but he leans over. Is that
okay, honey? So, uh, so that that was
really fun. I enjoyed dawning astronaut
gloves and astronaut um uh suit and
attempting to perform some of the
repairs that the Hubble repair
astronauts were going to do on orbit.
And I did that at a mockup of the Hubble
telescope. And that was fun to just see
the tools that they would be using and
to attempt that repair, which by the way
was successful uh by all measures.
Hubble has a literal new lease on life.
will go for another five, possibly 10
years. There's one we just did recently
about taste. That was kind of fun. I
think it just aired
on Tuesday night. Did Did anybody see it
Tuesday night? That had my mother in it.
Did you see my mother? Yeah. Yeah. Uh
she was commenting on whether I was a
picky eater as a child. And just
briefly, just so you know, vegetables
are bitter. And the question is, how
come kids don't like vegetables, but
adults do? And the answer is most plant
matter that would kill you in the wild
has a bitter taste.
And so if you are a child and happen to
like bitter tastes, you're dead. Okay.
So So or more specifically, you don't
live long enough to have other children
who like bitter taste. So, and and
children are much more susceptible to
the same quantity of toxins that than
what an adult would be. And so, it so
it's not unrealistic to recognize that
children have a higher sensitivity to
bitter taste because they have a higher
susceptibility to the death of bitter
plants. And so what it means is if any
kids in the room who don't eat their
broccoli, you have genetic arguments to
lodge with your parents. So I enjoyed
that one because I got to taste
different foods, really nasty bitty
bitter foods. I got to taste the most
bitter liquid substance in existence.
It's called Bitrex.
And just so you understand, if you put
one drop on your finger and touch it to
your tongue,
which I did, it was by far the most
bitter sensation I had ever experienced.
And it stayed in my mouth for like 8
hours. And and I was I was kind of macho
about it. I said, "Well, it tastes like
concentrated
Guinness stout
in a hot day with you can I could
construct the extremity of that flavor.
I could do that." They gave others cuz
now the production staff was curious
like the lighting guy and I want to
taste it. They taste it. They One of
them had to run and throw up. Okay.
So, it was severe
severe. I also got to taste a tea from
Brazil that knocks out all of your
sensation of sweetness for about 30
minutes. And what's cool about that is
you you drink this tea, you swish it in
your mouth. You cannot so it binds to
the sweet sensors of your tongue,
preventing other sweet sensations from
being received. So it basically blocks
it's a chemical blocker. And so then
they they then gave me granulated sugar
and it was as though someone had put
sand in my mouth because that's the
texture of sugar but I couldn't taste
sweetness. So all I notice is that it's
sandy. So this is a sandy substance
that's dissolving in my mouth. And so so
I got to be a subject of these
experiments as well as one who reports
on them. And so those for me are the
most fun among them. So, let me just
mention that the Hubble story will be on
in our last program. We actually have
been following the training of the
astronauts that repaired the Hubble and
so it will be we've updated last year's
story and that'll be on I think the last
week of August, but you'll you'll have
to check your local listings and it will
also be on NOVA for full hour with all
the results at uh in October.
