[Music] okay Chris I am ready to make the vomit Factory what do I do first of all get your balloon
and attach it to the bottom of the funnel now get the bicarbonate of soda two or three big spoonfuls
will do in this case the funnel is representing the mouth the neck of the funnel is the oesophagus
the tube that goes from the back of your mouth down through your chest to your stomach in your
abdomen and the balloon is the stomach itself the next step is to make the food that's going
to get vomited in the plastic bottle so xand put lots of vinegar into the plastic bottle
half of that bottle now vinegar has got an acid in it called acetic acid acid when the
acetic acid mixes with the bicarbonate of soda it reacts and releases a gas called carbon dioxide
and that is going to build up pressure in the balloon and it's going to drive the vomit Factory
there we go Chris half a bottle of vinegar so let's add a couple of drops of food coloring
this has particularly puketastic mess potential so lay down lots of protective stuff wear an apron
and make sure that you have adult supervision so let's add two drops of green and then just a few
drops of yellow yellow [Music] good that's enough right Don't Panic Chris it's only food coloring
it's only vomit that's enough that's enough look at that you're the most cautious food colouring user in history well now
we're going to add some green peas chunks of carrot what appears to be carrot in vomit is actually part of
your stomach lining this mixes with these food scraps which is undigested food in your stomach
and then finally some washing up Liquid now in your vomit you've got lots and lots of mucus
from your saliva that you've produced and also from the stomach mucus itself and that's gonna
foam up that's why we're adding the detergent but it's looking good it is looking good it's a
perfect vomit mixture it is so now what Xand's gonna do is connect the balloon to the top of
the bottle but taking great care not to mix the contents yet those are now ready to be mixed I'm
gonna hand them to Chris because I will be doing the cinematography of this scene using 360 degree
vomit cam now it's a good time to remind you what happens when you vomit first of all you get that
feeling that something bad's gonna happen the nausea the sense of impending doom and that's your cue to
get to a bucket or a bathtub or a toilet or a sink next thing that happens is you take a deep breath and
you close your epiglottis so that no vomit can get into your lungs and what happens then Chris this is the stomach the pyloric
sphincter and that will close so that when the stomach squeezes it doesn't Force the food further
down the gut but it also closes for the time being the oesophageal sphincter which is the ring
of muscle we saw in the pig's stomach that stops food normally going back up towards your mouth
are you ready Xand I'm ready I've got the vomit cam on it here we go force that keep squeezing it
oh careful that's good now the bicarb and the acid have started to react and produce carbon
dioxide so the pressure inside the stomach is now Rising the gastroesophageal sphincter is
going to open and the stomach's gonna squeeze out all the food at once are you ready Chris i'm ready
it's going to blow it's puke time
[Laughter]
that's horrendous wow look at the speed and power of that your stomach and abdominal
muscles have all contracted to force the vomit out you've got it all over my kitchen Chris what
are you doing I'm really sorry about that it turns out my vomit Factory is too good
