I thought the water degraded the effect of the mentos?

somewhat but thats why u need to use more than one when doing this

so what if someone's smart and looks at their icecubes first before putting them in the soda?

they are suppose to be put into a container not left in the tray like you have a container with several inside and leave them somewhere that would be inconvenient to your victim my choice was my friends bed when he was sleeping

I get what you're saying now, that's devious, you my friend are an asshole! (mean it in a good way)
