So, back when we had Advanced Classes (I was in it, with about 11 other people), our teacher was explaining momentum.

So he stacked a basketball over a tennis ball in his hand and droppes them. The basketball flew across the room.

So, it being a science experiment, we had to record our thoughts.

But we, being 5th graders, were immature. Everytime our teacher would say balls, we would laugh.

The rest of that year, he called them spherical objects.

That is all.
