Mentos Rockets

2/1/2011By 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! http://www.youtube.com/watch?v=SkRcEGkdj9U

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.
