As part of our investigation into Solids, Liquids and Gas we carried out an experiment on Thursday.
We had already seen an experiment that was similar to this on You Tube but wanted to try it out for ourselves.
QUESTION: What will happen when Mentos are put into Pepsi and Mapsi Max.
HYPOTHESIS: The pepsi will froth up.
MATERIALS: Pepsi, Pepsi Max, Mentos, Tube
1. Take all of the materials to an area outside
2. Put funnel/tube into top of both bottles
3. Drop 3 Mentos into the funnel of the Pepsi and move away quickly
4. Drop 3 mentor into the funnel of the Pepsi Max and move away even more quickly!
FINDINGS: Both types of Pepsi fizzed up and went over the top. The Pepsi Max fizzed up way more than the Pepsi though.
CONCLUSION: The roughness of the Mentos combined with the extra chemicals in Pepsi Max make for a more impressive reaction.
