put the mentos in when you want it to fizz....or you can try tape. put the mentos on the tape the stick it to the edge of the opening then throw it and itll fizz. make sure the mentos dosnt touch the coke before you throw it.
Mentos makes a geyser shaking it just make it fizz over the top but if you take diet coke and two mentos put in the mentos then the top really quick and shake it up and throw it on the street (far away from you) you will be pretty satisfied.

Put the mentos in the Diet Pepsi and shake it up really good then quickly take the cap of and back up.

It depends what type of mentos you are using. The mint mentos will make it have a bigger impact. Other flavors, like grape or green apple, will not make it fizz as much. Try getting mentos mintensity and placing it into the coke. I'm not sure if it has any stronger effect or not, but it fizzes because the mentos hae little pores in them or something.. Go on YouTube and search up mythbusters mentos and coke. They will give better info.
Because of the carbon dioxide in the Mentos :)
