twister with a bad attitude
experimental and how many rubber ducks
will it take to rescue Gerald

experimental
welcome to experimental The Knockout
competition in search of the country's
sharpest science sharks we have two
teams bring out today in the red we have
from Newington School in Anand D Fria
please welcome Phillip Christopher Dean
and the green team are from deanway
school in deanway Conway they are shinos
Becka Fred those are the
teams now you don't have to be a rocket
scientist to understand the rules will
show both teams the beginning of an
experiment then using smarts sense and
science they have to work out how that
experiment is going to end they'll be
given all the relevant experimental
Equipment Plus advice from our science
analysis Matrix otherwise known as Sam
hey Sam any advice for today science is
an imaginative adventure of the Mind
seeking truth in a world of mystery
quite profound that isn't it let's get
on with our first experiment now outside
the research lab is our testing ground
and there you'll find our chief
experimental Holly
Willoughby welcome to the experimental
testing ground our first experiment
involves a race between our resident
technician Herby and three highly
dangerous fuses one is a rope soaked
with propellant one is made from black
powder and the third is a top secret
m*llitary Brown fuse which is made from
well I actually can't tell you that cuz
it's a secret so the challenge facing
our teams is to work out which fuse will
get to that barrel of gunpowder first or
will heroic Herby get there and disarm
it confident herbs yeah okay that's your
challenge guys and your time to
experiment Starts
[Music]
Now not even so Sam expl*sives highly
dangerous the teams should consider
whether the dampness of the testi grass
will affect the burning fuses gunpowder
was inv Ed 2,000 years ago by Chinese
scientists thank you very much Sam now
our teams have their fuse boards in
place by observing how long it will take
three short lengths of fuse to burn the
team should be able to calculate how
long Holly's 28 M of fuse will
take
not oh step back wow one
second R your time is down well done
there remember
remember to sorry remember to convert
all your time
[Music]
into1 okay guys your time is up I'm
going to need your predictions right
now we've got g*n powder 31.6 eight
seconds
we got g*n powder
28. 56 seconds let's see how their
answers tie into reality Holly right
Otis the whole area has been secured and
for safety reasons the fuses will be lit
electrically are you sure I'm going to
be able to outr run these three fusers
quietly confident Herby quietly
confident right let's start the
countdown on your marks get set go HBY
go run Herby run
run
[Music]
H come on HBY get up keep going
[Music]
run
[Music]
right Otis the outright winner was the
black powder followed very closely by
hery I'm all
right the gunpowder took 29 seconds to
burn at a speed of 0.8 m/ second the
Reds were 91% accurate and the greens
[Applause]
98 just over here in our control test
zone are two members of our
observational team who along with all
these objects will face the might of
these four electronic wind generators
all our teams have to do is decide which
of these objects will be blown away
first that's your test your time starts
[Music]
now is that heavy I don't
like Sam this has to be the easiest one
yet right hurricanes her when warm air
meets cold hurricane winds can reach 200
mph and do a lot of damage whereas the
laboratory fans can only blow off a few
[Music]
hats
would you say that being full of hot
hair is the same as being a bag of wind
wind is a smelly human concept unlike my
bubbles which are
purified
[Music]
the
that okay guys time's up hand me your
papers and I will read out your lists
thank
you okay red team
first tissues poly cups newspaper clear
cups hat plastic cup
plate Green Team tissue poly cup hat
small cup paper big cup and plate let's
see how Theory ties in with fact now our
teams didn't have an umbrella so we've
removed that start the fans
please and stop the fans
please only four objects were blown off
the table in this order poly cups
tissues newspaper and clear
cups
[Music]
[Applause]
the greens were 14% accurate given them
a total of 112 the Reds were 28%
accurate and their total is
119 so with the Reds currently in the
lead let's go back outside to our
testing ground for our next stunt Holly
Gerald our resident crashed his dummy
fancied himself as a bit of a James Bond
so kindly we've agreed to let him have a
starring role in his very own
experiment so for this program only the
challenge facing our teams is to work
out how many rubber ducks Herby will
have to attach to Gerald to lift him to
the surface quack quack so how many
ducks will it take to raise Gerald to
the surface like the merry Rose your
time Starts
Now by measuring how much weight one
rubber duck can support in the water
they should be able to estimate how many
it will take to lift Gerald Sam Duck's
raising a man from the bottom of a water
t*nk it's not very James Bond is it
another human error Gerald is not a man
Gerald is a crash test dummy and a
scientific Lifesaver some Crash Test
Dummies cost thousands of pound Gerald
cost
[Music]
86 we got
more so what is it you guys are looking
for
here
420 I will not
[Music]
bring they won't have anything that
[Music]
time
[Music]
okay teams time's up I need your
predictions Now 50 Ducks 42 Ducks let's
see how many ducks it takes
Holly right Herby is now in position
ready to attach the rubber ducks now the
rubber ducks are grouped in bunches of
five which just makes it easier for
Herby to attach them to Gerald so Herby
you've had your starters orders get
quacking
[Music]
how many bunches have be on there eight
eight you got eight on
there there you go there's Gerald's head
right there in the middle of all those d
okay oans from our experiment you could
see that it took nine Bunches of rubber
ducks to lift Gerald to the surface so
that's 45 rubber ducks in total to Sav
Gerald's life we're such a caring team
here with 93% accuracy the Green Team
take their total up to 205 points the
Reds were 89% accurate and their score
goes up to
[Applause]
208 that makes the Reds from Mo schol in
an and D frer this week's winners but
both teams go up onto our
[Applause]
leaderboard at the end of the series the
top two teams on our leaderboard will
battle it out in the grand finale but
right now it's the red team's turn to
predict the outcome of our fourth and
final stunt it's The Fabulous Furniture
flingor
po our final game gives the winning team
a chance to bump up their points of it
by simply guessing how far this nitrogen
Cannon can fling Furniture there's a lot
of options but as always the choices up
to you are observational team right
observational team what gets flung first
choose
now
table
table
table right whilst Herby loaves the
dining room table and chairs onto the
furniture flinger I want to remind you
of the Third member our team our
resident crash test dummy Gerald now
Gerald was only saying to me this
morning that he wanted to go up in the
world so I say to you Gerald now's a
chance so that's it guys how far will a
ram throw the dining table you have 10
seconds starting now and here's a brief
clue on the last show we fired a
wardrobe which was slightly lighter than
the dining table and that went
23.4
M okay guys your time's up give me your
answer 21.5 M okay let's see how Red's
guess ties in with fact
Holly the table and chairs are loaded
Gerald is in position the whole area has
been cleared for safety reasons so Herby
let her
[Music]
[Applause]
rip okay o to the official measurement
of how far that table flew is 20 M and
10
cm the Reds were 93% accurate bringing
their grand total to 301 that places
them third on our
leaderboard but will their grip be
strong enough for them to stay there
until next time make sure you join us
when another two teams will be taking a
sideways look at science with a
primitive rocket powered by a
firelighter a team of carjacking kids
and a stunt man worth his weight in sand
see you next
[Applause]
