i have here two balloons now mine is ignite healthy mucus-free balloons and i'm afraid
yours is very badly infected as you can see from the large amount of mucus in the airway
now let's inflate the balloons three two one
but this doesn't feel fair chris my mucous filled balloon is really hard to blow up
you can see my balloon inflates extremely easily and also
deflates extremely easily how's it going zond very badly i've got a mouthful of mucus and i
can barely get any air into this lung seems to me zone that you should have a bit of a cough
that'll make me feel much better okay ready three two one
there we go when you cough all the muscles around your chest and abdomen contract suddenly
this creates enough force to eject the mucus up your trachea and out of your mouth
like the mucus coming out of this balloon
now that has nicely cleared the mucus from zarn's airways and now his lungs are clear again
oh son what have you been eating voting is completely natural it's just your body's
way of getting rid of unwanted built up gas and everyone does it about 14 times a day
doesn't matter if we're talking about your head teacher or the queen herself we all do it and it's
honestly not your fault he is actually right there inside your large intestines there are
millions of good bacteria that are there to help break down food and as they eat they produce a
mixture of gases which is what makes you let rip this combination of gases is made up mainly of
carbon dioxide hydrogen sulfide and methane and the methane contains a lot of energy we're about
to show you and for this i'm going to need a special piece of equipment chris's hand
now this is a cylinder of methane and i'm going to release one day's worth of farts this experiment
is highly dangerous we're in a controlled lab using specially manufactured gas don't even
think about trying this yourself get your hand wet now scoop up those bubbles that's
right hold them well away from you i don't like the look of this ah what's up that was amazing
so that's how much energy there is in a day's worth of farms exactly that's one day's worth
of farts but you know what we have to do now a week's worth precisely one week's worth of farts
that's really good isn't it so we've done a day
we've done a week dare we do a month yes we do dare do it here we go ice it
wow that was amazing wow so we've shown you just how incredible your intestines are and how much
energy there is in your farts remember when you let rip it's an essential part of how your body
gets rid of excess gas and now you know whose fault it is that you do them in the first place
those cheeky little gut bacteria but if they weren't in our intestines we'd end up with
undigested foods sitting in there forever so there really is no reason to be ashamed of your
now we've got an experiment where we're going to separate the water from the toxins
in chris's urine and then chris is going to drink it what this may seem like a terrible
idea but chris won't actually be drinking weed he'll be drinking pure water extracted from it
so as we heat the urine the water vapor is evaporating and boiling off here and then being
cooled by the liquid in this tube and then just dripping out there right now your kidneys are busy
separating out water from waste toxins only they don't need all this kid they just do it naturally
it's amazing isn't it in just this tiny distance you go from filthy disgusting undrinkable urine
just along this tube and into clear refreshing delicious water i mean that is amazing isn't
it and if that was water your kidneys had separated out it would now be distributed
to all your organs and muscles to keep them working properly it doesn't smell like water oh
no it doesn't you're still going to have to drink it though you told everyone you would i didn't say
to anyone i was gonna drink it well i'm not going to drink it it's not my urine fine i will drink it
i can't believe he drank it actually it smells bad but it doesn't taste bad
which i'm very happy about without water your body simply wouldn't work and you can help your kidneys
do the best job they can just by drinking plenty of water every day if you're weaning regularly
and it's light in color you'll know you're helping your body remember i've been on the healthy diet
ready oh now it does look like poo certainly smells like poo poo smells because of all the
bacteria in your digestive system as everything gets broken down they release a lot of gas and
smelly chemicals so it's less porridgey than it was on day one but that's because i didn't drink
enough water there is something else interesting to see your body can't break down the fiber in
food like the shell on a piece of sweet corn i've been eating a lot of sweet corn recently
so i can show you if you have a look here that is an undigested piece of sweet corn
you
