How does it take to start and finish the rate of reaction where
a substrate (mentos) are placed in different types of soft drinks?
Will the amount of the substrates affect the reaction? And will the
temperature affect the explosion?
Slide 4
Slide 5
There are many factors that can affect the reaction of the
explosion: Temperature of the soft drink Different type of sodas
The amount of mentos
Slide 6
Amount of mentos will affect the duration of the reaction
Different sodas will affect the height of the reaction
explosion
Slide 7
Cold temperature will lessen the reaction Hot temperature will
ignite a higher reaction Constant room temperature will act as a
medium of the reaction

Slide 10
Mentos during the three trials, amount of metos will be
different due to the reason that it is needed for chemistry to see
which amount (5 piece, 10 piece, or 15 piece) has the greatest
reaction
Slide 11
The duration of the reaction when different amounts of Menthos
react with sodas
Slide 12
Size of Menthos- Each piece of mentos will have same shape and
size. This will allow equal chance for every soda to have a
reaction. Temperatures- The liquid will be placed under the same
room temperature 24*C to keep a steady reaction not to boost or
slow down the reaction, more than the mentos will. Volume- The
Liter (L) of the solution will be the same (1,5 L) so everything
would be equal in having the opportunity to react.

Slide 14
Type of Soda The different type of soda will provide different
height of the reaction. By changing the sodas, there will be
different amount of sugar that will contribute to the reaction of
the CO 2.. This will help to the extent whether each soda will have
different height and duration of the reaction.
Slide 15
The effect of the different sodas on the reaction with Mentos.
This will show a trend of the reaction rate, in order to draw a
general conclusion whether the different amount of mentos will
affect the soft drinks. The duration of the reaction Mentos give to
the different sodas. This will determine whether the type of the
soda will affect the rate of the reaction. The height of the mentos
explosion. This will determine whether the amount of the mentos
really affects the height of the explosion rate. This variable is
essential to gather a constant range of datas.
Slide 16
Sizes of Mentos - each package of this candy when sold will be
weighted to a specific number, meaning each piece that is presented
in the round but flat form has the same size. This will allow equal
chance for every soda to have a reaction. Temperatures the liquid
will be placed under the same room temperature (24c) to keep a
steady reaction not to boost or slow down the reaction, more than
the Menthos will. Volume the liter (L) of the solution will be the
same (1,5 L) so everything would be equal in having the opportunity
to react.

1. Prepare all materials 2. Place one bottle of 1.5 Liters of
soda on a flat surface 3. Prepare the mentos (depending on the
amount could range from 5, 10, & 15 mentos) 4. Place the ruler
at the neck of the bottle 5. Open the bottle 6. Quickly insert the
mentos 7. Start counting the stopwatch 8. Measure the height with
the ruler 9. Record the data 10. Repeat for 3 trials to get optimum
data.
Slide 27
1. Prepare all the 9 mini Coca Cola Zero 2. Put 3 drinks inside
a frige and cool it until 15*C 3. 3 will need to be heated by using
a water bath 1. Fill 500 mL of water in the 500 ml beaker 2. Heat
the water filled beaker by using a hotplate 3. Place thermometer 4.
Wait until the water bath is 60*C 5. Then place the Coca-Cola Zero
inside of it for 10 minutes
Slide 28
4. While waiting for the heating and cooling process place 5
mentos inside of the room temperature Coca Cola Zero 5. Measure the
height and time when the reaction occur 6. Repeat the step with the
cold and hot coke zero

From the Graph above, we can see that as the temperature of the
Coke Zero increases, than the time of the reaction from start to
finish will be shorter. From the graph, we can also see that the
random error is big; we can see this from the points that are not
close to the best fit line. This random error is probably caused by
the errors we make when we are doing the methods.
Slide 38
From the first graph, we can see that as the temperature
increases, than the height of the reaction also increases. However
this data of the two variables are not directly proportional to
each other. This can be proven as we see from the graph when the
best fit line doesnt intercept the origin which is 0.
Slide 39
Slide 40
Sprite has the highest average amount of explosion Fanta has
the longest duration of the reaction Coke is in between of the two
Reaction occurs because of the Nucleation process where CO2 fuse
with the pores of the mentos to create the bubbles or foam Soft
drinks with mentos is currently safe to enter your digestive
system.
Slide 41
Nucleation occurs when the mentos reaches the surface of the
soda. The more mentos is inserted to the soda it is where the most
and the fastest reaction is from When less mentos is inserted to
the soda it is where the least and the longest reaction occurs
Slide 42
Pressure is what helps an explosion occurs, not only that but
the CO2 placed inside the bottle needs to go somewhere when opened
or when reacting with mentos. Higher temperature means higher
pressure Therefore, the higher the temperature is, the higher the
height of reaction and the faster the time of reaction While, the
lower the temperature is, the height would also be low and the time
would be then longer than the usual.
Slide 43
Slide 44
The strength of this experiment for all three discipline is
that it turned out to be successful. With a table filled with
results and by bringing all the specific and right materials. Not
only that but the group collaborated well and accepted ideas from
other members. Everyone overall did their job equally. The weakness
is that we didnt completely have the right procedures to do this
experiment because of underestimating that it would be easy. So
there were a slight miscommunication and lack of materials at first
even in the end we were able to overcome it. What we would need to
improve if were to do this again is one use a camera that would
catch all the specific detail that an eye could not. Secondly, use
gloves because the experiment could get messy. Then, we should
bring an apparatus that could help us put the mentos in quickly and
tidily not like how we did it before.
Slide 45
Many children are curious and do not know the real effect of
combining soft drinks with mentos, even adults. That is why rumors
have it that people could die consuming these two product together.
So we did this experiment to research the real situation and also
to help the society raise awareness. Giving better knowledge to
whom who does not understand the effect of soft drink combined with
mint candies.
