This was a great game for our youth. There is some kind of science principle that makes Diet Coke erupt like a volcano when you drop Mentos in it. This only works with “diet,” not regular. The more Mentos you can drop in at once, the bigger the eruption.
Before the game, find a spot next to a wall where the Diet Coke can spill everywhere without creating a mess. Grass is good, because sidewalks and parking lots can get sticky. On this wall, make a vertical line with the masking tape. Use the tape measure to mark off 1 ft. 2 ft. 3 ft. etc. on the tape and draw thick lines at those intervals with the sharpie. You’ll need the ladder to get up high, and 9-10 ft. should be plenty. The lines need to be dark enough that your camera can see them from a safe distance away.
Divide your youth into several teams of 5 or so members. You need as many 2 liters of Diet Coke and packs of Mentos as you have teams. Give the teams 5 min. to use the paper and items to create a cone or some object to deliver the most Mentos into the bottle. Set up the first bottle in front of the tape, and position the camera a safe distance away and start recording. Let the first team go to drop their Mentos in the bottle and make an eruption. Move the used bottle away, and put another one there for the next team. Each bottle needs to be in the same place, so you may want to mark that spot with a piece of tape. After the last team, head inside to watch the footage and see which team won with the highest eruption.
