How Many Balls Are In This Cup?Added:
You know those challenges where you have to try to guess the exact amount of jelly beans in a jar? Well, that's a mobile game now. And I am going to be playing this game until I can perfectly guess the number of things in the jar.
And if I actually guess the perfect number, you guys have to promise to like and subscribe. Let's do this. How many balls are in this cup? Oh my gosh, that looks like a lot. Not going to lie, I think that's around like 87. Submit.
Here we go. Oh my gosh, it is. Wow.
