## Transcript

Oh yeah. CREW: Oh yeah. Yeah? CREW: Yeah. Do you know what I'm talking about? CREW: [INAUDIBLE] go faster and faster. Yeah, I've seen people do this before. But you've never done this before? No. Michael, when did you grow up? The '90s. We're, like, pretty close. The 1790s. Hand-clapping hadn't been invented yet. Can you tell us-- MICHAEL... Read More

### Q: How can a ping-pong ball stop and turn around to come back without bouncing off anything?

By throwing the ball straight up, it will stop at the top momentarily and then start moving down, coming right back to the thrower.

### Q: What happens to the water level when a diamond inside an ice cube falls to the bottom of a glass of water?

The water level stays the same because the diamond is more dense than water, so it displaces its own weight in water.

### Q: What is the relationship between hand-clapping and its history?

Hand-clapping is a rhythmic action where two hands hit each other to produce sound. Its origins can be traced back to the 18th century.

### Q: Why does a ball thrown straight up in the air stop momentarily at its highest point?

The ball's continuous motion causes it to pass through the top point in an instant, briefly stopping before reversing its direction due to gravity.
