Mentos Rockets
2/1/2011
By Dominick Mack
With help from Siri Jonsson
Abstract:
 This experiment tested whether Diet Coke or Pepsi
worked better in a Mentos rocket.
 Nether rocket worked in this experiment, so we did not
find an answer to our question.
Question:
 Witch goes higher; Diet Coke or Pepsi with
mentos?
Hypothesis:
 Diet Pepsi will go higher than diet Coke.
Research:
 I went to google and youtube.com. I watched
a series of videos about Mentos rockets.
Each website I went to I learned different
techniques on how to throw the bottles and
when to run.
Materials:
 Diet Coke, Diet Pepsi , Mentos , two bottles , scotch
tape. Safety goggles
Procedure:
 Fill a bottle with Diet Coke. Fill a bottle with
Diet Pepsi. Use Scotch tape to tape three
mentos together. Drop it into the bottle.
Tighten, shake well and slam it on the
ground.RUN!

Dominick shoots off his rocket.
Summary of Results:
 Both bottles did not shoot as a rocket. They
just fizzed out of the bottle.
Conclusion:
 This experiment did not confirm which was
better. A bit disappointing. If I ever try this
again, I will practice throwing the bottles with
water and use bigger bottles on different
surfaces such as rocky, flat, wood, and
pavement.
Journal Entries:
 1/20/2011 I found two bottles to use. Made a note to get
mentos from the store. Got fins for the bottles, and brought
them home.
 1/25/2011 I cut the fins out for my bottles. Went to the
store and brought the mentos and pop home. I researched
about my science experiment.
 1/26/2011 Updated journal and thought where we should
do the experiment.
