    Would that even work? As the ice melts, only a small part of the mentos would be exposed, with a gradually increasing surface area. But I’d expected it only works because of the whole surface being suddenly exposed.

      No, for several reasons.

      Ice would expose mentos way too slowly. Mentos being in water and freezing would have already removed the texture that makes it work to begin with. By the time the ice melted enough a lot of the carbonation would have already escaped the soda. One mentor isn’t enough to cause much reaction. The soda would be cold from the ice and that slows the release of the cO2…

        Poor it along the side of the glass, you animal.

          Yes, however the (oh god no! I’m being that guy!!) pouring it into the glass even carefully down the side loses the carbonation that “makes” the mentos and coke work. You really can only do it from in the bottle

            Really? Are you sure it’s not just the shape of the bottle vs a glass? I’m not super familiar with the reaction, myself. Never heard about it not working in a glass.

              You need to drop the mentos in pretty quickly after opening the soda, because even the loss of pressure reduces the reaction fast

                Huh, interesting.
