 Scientists, take a look over here. I did turn into a ball. They are not big or small. I want you to take both pieces and want you to hold them in your hand, like this. Match me. What do you notice about the weight? Do you think they're the same? Yeah. I need a scientist to come out and check. I brought our scale, so we're going to check. Rory, can you bring both of your pieces over and put them into the scale? What do you notice? That one's heavier. Just a tiny bit heavier, but pretty much they're the same.
