Coca Cola in pool with mentos

For Math's in Miss Goslin's class we had to watch this video where this guy fills his pool up with coca cola and we had see how much liters or gallons there was in a pool.And my answer was 1,500 gallons.Once they put all of the coca cola in they put a 2 liter bucket full of Mentos they chucked it in and it started to fizz up .Then they jumped into the pool and put the drone in to see what it looks like under without opening there eyes here's a video.
